Took a closer look at the study and the patient population was from a small town in Germany, Heidelberg. It'd probably be a fair guess that there's not a lot of variation in the patients' ethnicity so in this particular case controlling by race probably wasn't necessary.
This observation makes me more confident Vitamin D plays a role.
In any event, good to review studies for potential issues like this.

There might not be a lot of black people but Heidelberg is a university town and rather diverse. 27% are ethnic minorities, though only maybe 1% are black (4% Asian, 4% Russian/CIS, 3% southern Europe, 3% Turkey, 2% US-American, 2% Latin American, 2% Polish, 2% ex-Yugoslav)
