Sensitivity Analyses
We conducted a series of sensitivity analyses to test various assumptions. First, we ran the primary model with additional adjustment for age, sex, and active-duty status, as these were potential confounders identified a priori. Second, we ran the primary model excluding everyone without an RMDQ score at 1 year (25 of 270 [9.3%]) and then excluding individuals who reported their ability to access medical care had been affected by the COVID-19 pandemic (38 [14.1%]). Finally, we conducted a subgroup analysis comparing the primary outcome according to SBST risk group.
