Predictors of a New Depression Diagnosis Among Patients With Incident Diabetes and Matched Nondiabetic Patients

Parameter	Age-Sex Coefficient^a	PValue	Age-Sex-Visits Coefficient^a	PValue
PC=primary care.
^a A positive coefficient indicates an increased likelihood of a depression diagnosis after the index date; a negative coefficient indicates a decreased likelihood.
^b Age was centered around the mean of 57 years.
^c Number of primary care visits was centered around the median of 6.
