NR, not reported.
The main study (n = 158) did not report racial distribution (15); therefore, we included this substudy.
Some studies have missing data on race/ethnicity.
This is a multinational study including U.S. sites.
This study was not included in the final analysis, as they did not report race/ethnicity.
