  2. To adjust for potential confounders of clinically significant associated factors for the GM-ITE score, the following variables were incorporated in the multivariate analysis: chosen specialty, hospital type, hospital location, sex, number of post-graduate years, number of emergency department shifts per month, average daily number of inpatients for whom the resident provided care, average resident duty hours worked per week, and average time spent studying per week. When internal medicine (the future specialty chosen by the highest number of residents) was set as the reference, residents planning on choosing general medicine were the only ones who scored higher (coefficient 1.3792, 95% CI 0.07894–2.6796, p = 0.0376)
