Randomized Designs(隨機設計)到底是什麼？
Randomized Designs 隨機設計 - Statistical analyses appropriate for cluster-randomized designs were used, and structural equation modeling to estimate dose-response effects. [1] This chapter introduces permutation methods for multiple independent variables; that is, completely-randomized designs. [2] Moreover, from an objectivist worldview, there is a need for data concerning non-symptom measures that are specific to group-based music therapy experiences using randomized designs. [3] IS trials should be rigorous, striving for internally valid estimates of effect by adopting best practices, and deploying optimal nonrandomized designs where randomization is not feasible. [4] Then, approximately 25 years ago, certain statistical and pharmacological considerations ignited a debate around whether randomized designs should be used instead. [5] Well implemented, randomized designs will strengthen the current evidence base substantially. [6] Finally, we propose the combination of all these types of studies to obtain reliable head-to-head drug comparisons in the absence of randomized designs. [7] Although RWE could come from randomized or nonrandomized designs, there are significant concerns about the validity of RWE assessing medication effectiveness based on nonrandomized designs. [8] Study selection will follow the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and study quality will be assessed by the CONSORT checklist for randomized controlled trials (RCTs), transparent reporting of evaluations with nonrandomized designs (TREND) checklist for nonrandomized controlled trials (NRCTs), and CONSORT extension for pilot and feasibility studies for pilot studies. [9] We provide methods for a priori power analysis in three-level polynomial change models for block-randomized designs. [10] Results The literature review identified 29 articles that were pertinent to the research question that used either cross-sectional, prospective cohort, or randomized designs. [11] STUDY SELECTION: Selected studies were published from January 2000 to 2019, included randomized and nonrandomized designs with pretest and posttest data, and assessed substance use, mental health problems, or violence victimization outcomes among SGMY. [12] Objectives: We develop simple formulas to adjust statistical power, minimum detectable effect (MDE), and optimal sample allocation formulas for two-level cluster- and multisite-randomized designs when the outcome is subject to measurement error. [13] This experiment used randomized designs with four treatment and four replications. [14] We discuss the problems associated with conceptualizing the changing criterion design as a variant of the multiple baseline design, the potential of the range-bound changing criterion design, experimental control as an all-or-none phenomenon, the necessity of random assignment for the statistical-conclusion validity of the randomization test, and the use of randomization tests in nonrandomized designs. [15] As a result, we propose to carry out a prospective, controlled, nonrandomized TREND-study design (Transparent Reporting of Evaluations with Non-randomized Designs-TREND) in a large sample of 416 patients (208 per group) in order to assess the use of intracorporeal side-to-side ileo-colic laparoscopic anastomosis as the gold standard in right hemicolectomy. [16] Further controlled studies with randomized designs are needed to investigate these promising results in more depth. [17] Although several quality appraisal tools are available for intervention studies, fewer tools are available for non-randomized designs, especially for studies of measurement properties. [18] However, the results shall be taken with caution due to the non-randomized designs and other methodologically deficits in the majority of the included studies. [19] Inclusion criteria were: self-described palliative care intervention studies using randomized designs for participants with lifelimiting illnesses aged 18 years or older. [20] Eligible studies used randomized designs, evaluated interventions initiated within 3 months of potentially traumatic medical events, included adult participants, and did not have high risk of bias. [21] Study sample size ranged widely, and most used cluster-randomized designs, recruited undergraduate college students, and evaluated a multisession program delivered via group sessions. [22]使用適合集群隨機設計的統計分析，並使用結構方程模型來估計劑量反應效應。 [1] 本章介紹了多個自變量的置換方法；也就是說，完全隨機的設計。 [2] 此外，從客觀主義的世界觀來看，需要有關使用隨機設計的基於小組的音樂治療體驗的非症狀測量數據。 [3] IS 試驗應該是嚴格的，通過採用最佳實踐來爭取內部有效的效果估計，並在隨機化不可行的情況下部署最佳非隨機化設計。 [4] 然後，大約 25 年前，某些統計和藥理學考慮引發了關於是否應該使用隨機設計的爭論。 [5] 實施良好的隨機設計將大大加強當前的證據基礎。 [6] 最後，我們建議將所有這些類型的研究結合起來，以便在沒有隨機設計的情況下獲得可靠的頭對頭藥物比較。 [7] 儘管 RWE 可能來自隨機或非隨機設計，但對於基於非隨機設計的 RWE 評估藥物有效性的有效性存在重大擔憂。 [8] 研究選擇將遵循系統評價和薈萃分析 (PRISMA) 指南的首選報告項目，研究質量將通過隨機對照試驗 (RCT) 的 CONSORT 清單、非隨機設計評估的透明報告 (TREND) 清單進行評估對照試驗 (NRCT)，以及試點研究的 CONSORT 擴展和可行性研究。 [9] 我們為塊隨機設計的三級多項式變化模型提供了先驗功率分析方法。 [10] 結果 文獻回顧確定了 29 篇與研究問題相關的文章，這些文章使用了橫斷面、前瞻性隊列或隨機設計。 [11] 研究選擇：選定的研究發表於 2000 年 1 月至 2019 年，包括具有前測和後測數據的隨機和非隨機設計，並評估了 SGMY 中的物質使用、心理健康問題或暴力受害結果。 [12] 目標：我們開發了簡單的公式來調整統計功效、最小可檢測效應 (MDE) 和最佳樣本分配公式，用於當結果受到測量誤差時的兩級集群和多站點隨機設計。 [13] 該實驗使用具有四次處理和四次重複的隨機設計。 [14] 我們討論了與將變化標准設計概念化為多基線設計的變體相關的問題、範圍界限變化標准設計的潛力、作為全有或全無現象的實驗控制、隨機分配統計數據的必要性。 - 隨機化測試的結論有效性，以及在非隨機設計中使用隨機化測試。 [15] 因此，我們建議在 416 名患者（每組 208 名）的大樣本中進行前瞻性、對照、非隨機趨勢研究設計（透明報告評估與非隨機設計-趨勢），以評估使用體外迴腸結腸腹腔鏡下側側吻合術作為右半結腸切除術的金標準。 [16] 需要進一步的隨機設計對照研究來更深入地研究這些有希望的結果。 [17] 儘管有幾種質量評估工具可用於乾預研究，但可用於非隨機設計的工具較少，特別是對於測量特性的研究。 [18] 然而，由於大多數納入研究的非隨機設計和其他方法學缺陷，應謹慎對待結果。 [19] 納入標準是：自我描述的姑息治療干預研究，使用隨機設計，針對年齡在 18 歲或以上的患有限制生命的疾病的參與者。 [20] 符合條件的研究使用了隨機設計，評估了在潛在創傷性醫療事件發生後 3 個月內開始的干預措施，包括成年參與者，並且沒有高偏倚風險。 [21] 研究樣本量範圍很廣，大多數使用集群隨機設計，招募本科生，並評估通過小組課程提供的多課程計劃。 [22]
Completely Randomized Designs 完全隨機設計
The research was arranged with Completely Randomized Designs with the concentration of GMS (0. [1] The dbayes and pbayes tests were previously implemented in the context of completely randomized designs by one of the authors. [2] Study Design: The experiments comprised completely randomized designs: Seven treatments with five replicates on in vitro test; and four treatments with five replicates each, on in vivo test. [3] Completely randomized designs lend themselves very easily to the assumption that all the effects are of equal interest. [4] The experiment was conducted by using 2 factorial completely randomized designs. [5] The implementation of these tests in the context of completely randomized designs has already been performed in code R. [6] The designs have been obtained using the A-optimal completely randomized designs and modified strongest treatment interchange algorithm. [7] The dbayes and pbayes tests were previously implemented in the context of completely randomized designs by one of the authors. [8] The investigation was carried out for 90 days in 3 x 3 completely randomized designs.

[1] dbayes 和 pbayes 測試以前是由其中一位作者在完全隨機設計的背景下實施的。 [2] 研究設計：實驗包括完全隨機的設計：體外試驗七次處理，五次重複；和四個處理，每個處理五個重複，在體內測試中。 [3] 完全隨機的設計很容易假設所有效應都具有相同的興趣。 [4] 該實驗採用 2 個因子完全隨機設計進行。 [5] 這些測試在完全隨機設計的上下文中的實現已經在代碼 R 中執行。 [6] 這些設計是使用 A 最優完全隨機設計和修改後的最強治療互換算法獲得的。 [7] dbayes 和 pbayes 測試以前是由其中一位作者在完全隨機設計的背景下實施的。 [8] 調查以 3 x 3 完全隨機設計進行了 90 天。 [9] 這項研究採用完全隨機設計 (CRD) 進行，其中一個因素是味精劑量（0、3、6 和 9 g）。 [10]
