Bold type indicates statistical significance.
*
Personal perception of type 2 diabetes risk was categorized as lower (“slight chance” or “almost no chance”) or higher (“moderate chance” or “high chance”).
†
Nine participants did not answer the survey question on risk perception.
‡
A1C values were missing from the EHR for 123 participants, so A1C was not included as a covariate in our model.
