## What is/are Two Groups?

Two Groups - 69%, with a highly statistically significant difference between the two groups (P < 0.^{[1]}Twenty runners aged 36–40years were divided into two groups: with and without vitamin D3 supplementation (10,000units daily).

^{[2]}51), significantly higher in group C vs the other two groups.

^{[3]}Two groups were created, control and experimental.

^{[4]}METHODS In this multi-center randomized controlled trial undertaken between September 2014 and August 2016, 408 child-bearing age women who underwent induced abortion surgery and randomly assigned to two groups: MI group who received intramuscular MI treatment (n = 207) and no-treatment group (n = 201).

^{[5]}Participants were allocated to two groups norepinephrine group (n = 60), and phenylephrine group (n = 63).

^{[6]}Biochemical and anthropometric parameters before and after the intervention were compared between the two groups.

^{[7]}After adjusting patient variables by 1:1 propensity score matching, 45 patients were included in both the EU and CC groups, and no significant differences in major clinical characteristics were noted between these two groups.

^{[8]}Results: The analysis of variance (ANOVA) between the two groups for both the pretest and post test is conducted.

^{[9]}The accompanying microstructure and mechanical properties were also divided into two groups following texture coefficient.

^{[10]}The differences in antibacterial peptide LL-37, PCT and CRP levels between the two groups were compared.

^{[11]}Latent class analysis identified two groups: occasionally sick and healthier.

^{[12]}Moreover, the average UPDRS score of the observation group was significantly lower than those of the other two groups.

^{[13]}CD4 data were divided into two groups: CD4 < 200 cells/mm 3 and CD4 ≥ 200 cells/mm 3 and Mann-Whitney test was performed.

^{[14]}No significant differences were found in the adverse reactions such as nausea and vomiting in the two groups after the treatment (all P>0.

^{[15]}Growth traits, food intake and feed conversion ratio were recorded weekly and expressed as the difference between the two groups.

^{[16]}The nutritional status, GCS score, and APACHE II score were compared between the two groups.

^{[17]}Eligible pairs of mothers and their offspring (n=80) were randomized to two groups: propolis (n=40) and placebo (n=40).

^{[18]}The surgical conditions were statistically compared between two groups by Mann-Whitney U test.

^{[19]}According to different treatment methods, all patients were divided into two groups: emergency operation group (n=6), direct internal fixation after emergency debridement; staged operation group (n=16), emergency debridement and suture, performed the second period of fixed treatment after the soft tissue condition to improve.

^{[20]}We consider the problem of high-dimensional classification between two groups with unequal covariance matrices.

^{[21]}The study subjects were divided into two groups i.

^{[22]}RESULTS: The results of the experiments showed that there was a significant relationship between two groups and the age of the patients is significantly higher than the control group (p = 0.

^{[23]}The patients were divided into two groups by the age: 65â€“79 (group I) and ≥80 years (group II).

^{[24]}There was no significant difference in clinical data and survival rate (OS) between the two groups of patients and other complications.
