Diabetes diagnosis based on glucose control levels and time until diagnosis: a regression discontinuity approach to assess the effect on direct healthcare costs

Table 2 Descriptive statistics on healthcare use and costs for those treated (HbA1c ≥ 6.5%) vs. controls (HbA1c < 6.5%). Span = 6 months

	Average glucose control (HbA1c) < 6.5% N = 86,704		Average glucose control (HbA1c) ≥ 6.5% N = 72,774
	Mean	Median	Mean	Median
Number of medical visits	53.05	44.00	53.51**	44.00
Cost of medical visits	3,386.10	2,369.39	3,426.28**	2,365.76
Cost of procedures	4,356.75	0.00	4,521.05**	0.00
Drugs cost	690.52	0.00	646.33	0.00
Total costs during the first 6 months after the laboratory test	8,433.36	2,651.25	8,593.66	2,602.78
Accumulated costs during the 6 months before the laboratory test^a	467.57 (5,316.12)		305.13*** (3,573.81)

The stars represent the tests for statistical differences between means, which denote: *: p-value < 0.10; **: p-value < 0.05; ***: p-value < 0.01
