^aLength of follow‐up and average time between evaluations were calculated only for patients who had at least 2 serial observations (n = 111).

^bBaseline prevalence is the number of unique participants diagnosed with the corresponding psychiatric diagnosis at baseline.

^cIncidence is the number of unique participants who were diagnosed for the first time at a subsequent visit. The percentage is not provided for incidence because of participant attrition (changing sample size).

^dRemission indicates cases where a diagnosis was not made for a participant who was diagnosed at a prior evaluation; for which the number of relapsing cases is also provided.
