metan forest plot - how to display individual p value for each study

[YT Wang]

Hi all,

I really want to display the p value next to the effect size and the confidence interval for each study in the forest plot, I cant figure out a way to do it! Can anyone please help?

much thanks in advance

Dear Y T Wang,

The easiest way to achieve this is probably to manually calculate the p-values from the effect sizes and confidence intervals, store them in a new variable, and add it to the forest plot using the option rcols().

Note that p-values for individual studies are not typically displayed in the forest plot, which is (I think partly) why metan is not set up to do this automatically.

Best wishes,

David.

Sir, I was trying to add p-value to the forest plot, and I could not add the variable by entering the command "rcols()", how should I do it the right way? Thanks for your time.

rcols() is an option. You add options after the comma in the main command, so it’s more like

metan hr lower upper, … rcols(pvalue)
