| * Compares continuity score of 1.00 with continuity score of 0.00. | ||||||||
| † Number of outpatient visits during study year for which diabetes was listed as any of 3 diagnoses. | ||||||||
| ‡ Reference group is endocrinologist. | ||||||||
| § Reference group is 55-64 years. | ||||||||
| # Reference group is male. | ||||||||
| ¶ For each diabetic complication, comparison is presence vs absence of complication. | ||||||||
| # Reference group is nonmetropolitan. | ||||||||
| ** For each ambulatory diagnostic group (AGD), comparison is presence vs absence of ADG; only ADGs significant at P <.05 for 1 or more outcomes are included in this table. | ||||||||
