## What is/are Meta Analyses Involving?

Meta Analyses Involving - The bivariate model was used to estimate summary sensitivity and specificity for meta-analyses involving four or more studies; otherwise, random-effects logistic regression was used.^{[1]}We recommend using the stepwise-hierarchical pooled analysis approach for meta-analyses involving randomized and observational studies.

^{[2]}RESULTS Fourteen studies were included in the systematic review; 12 studies were included in meta-analyses involving 18,424 participants.

^{[3]}DESIGN Systematic review with meta-analyses involving multidimensional outcomes.

^{[4]}The bivariate model was used to estimate summary sensitivity and specificity with 95% confidence intervals for meta-analyses involving 4 or more studies, otherwise random-effects logistic regression was used.

^{[5]}Conclusions We recommend using the stepwise-hierarchical pooled analysis approach for meta-analyses involving randomized and observational studies.
