I was the analyst for the myPACE trial (published here in JAMA Cardiology), and needed to put together a subgroup analysis figure. I didn’t find any helpful stock code, so I wrote my own. The code uses the Frames feature that was introduced in Stata 16. It will (a) make a new frame with the …

If you like automating your Stata output, you have probably struggled with how to format P-values so they display in a format that is common in journals, namely: If P>0.05 and not close to 0.05, P has an equals sign and you round at the hundredth place E.g., P=0.2777 becomes P=0.28 If P is close …
What’s up with adding text to figures in Stata? It’s handy to add text to your plots to orient your readers to specific observations in your figures. You might opt to highlight a datapoint, add percentages to bars, or say what part of a figure range is good vs. bad. Adding text to Stata is …

Sometimes you want to combine two figures in Stata but the –graph combine– command isn’t doing it for you for whatever reason. I’ve run into this when I’ve already merged several figures (abcd), and want to combine that with another merged figure (1234): But what I want is one image that looks like this, stacking …

The below code outputs this Bland-Altman plot figure, which prints the mean and SD and puts a solid line for mean difference and red dotted lines for mean difference +/- 1.96*SD. (Note: the original BA paper used +/- 2*SD, but it’s reasonable to use +/-1.96*SD given it’s commonality in estimating the bounds of 95% confidence …

I recently had to make some scatterplots for Figure 3 of this paper. I decided to clean up the code in case it might be helpful to others. The below code outputs a scatterplot with R-squared and %CV. I grabbed the %CV-from-a-regression code from Mehmet Mehmetoglu’s CV program. (Type –ssc install cv– to grab that …
