    Please introduce more functions under the Meta package, especially these functions: label.right, label.left, label.e, label.c, these functions are more important than changing the color of the summary effect line, diamond and the effect size square of each study.

    Hi Dr. Mahmoud, thank you for the guide. I have a question, at timestamp 6:17 , is it necessary to delete the previous values and labels, and redo it?Is it possible to just edit the previous and click OK to update it? As in will it affect how SPPS registers/processes the reverse coding request?

    Thanks. This was very useful. How do we change the scale of X axis. I have a data sets where I want to estimate the survival curve in terms of hours and not days as survival time. Will appreciate if you can guide on this. Instead of “days” as time interval in the X axis, I want to change the scale to “hours” instead of “days”. Thanks a lot
