| Charlson Comorbidity Index: 6+ | 1.12 (1.01 to 1.24)* | 0.87 (0.67 to 1.13) |

Results of full logistic regression model of the odds of poor diabetes control, controlling for age, gender, Charlson Comorbidity Index category, number of mental and behavioral health diagnoses and Social Deprivation Index (SDI) score of the patient's census tract (OCHIN) or zip code tabulation area (HCN). SDI scores were calculated using national percentile ranks of the SDI. Diabetic patients were defined as those with at least one HbA1c measurement in 2015. Poor control was defined as HbA1c > 9 at the last test in 2015.
↵* Significant at the .05 level.
↵† Odds ratio for an increase of 1 unit (10 national percentile ranks) in score.
