Linear Regression is a statistical technique used to model the relationship between a dependent variable and one or more independent variables. It fits a straight line to predict outcomes based on input data. Commonly used in trend analysis and forecasting, it helps in making data-driven decisions ...

However, our a priori assumption was compatible with the latter. In the third step, we selected MH (Mantel–Haenszel) to run the fixed-effect and DL (DerSimonian and Laird) to run the random-effects models. Forest plots and funnel plots are the main outputs of this analysis step. One ...
