Figure 15From: An accurate test for homogeneity of odds ratios based on Cochran’s Q-statisticFitted line plot for the first moment of Q. Fitted line plot of the relative first moment of Q based on studies with equal parameters. The horizontal coordinate is the first moment (divided by K−1) as estimated using a theoretical expansion, and the vertical coordinate is the first moment (divided by K−1) as found from the simulations.Back to article page
