Table 6: Continuity of Care Index Results From Chen and Cheng’s Sensitivity Analysis by Visit Tertiles.

Variable		Hospitalization	ED Visits
		Odds Ratio (95% CI)	Odds Ratio (95% CI)
Low visit group (4–19 visits/year)
	Low continuity	1.00	1.00
	Medium continuity	0.59 (0.56–0.62)	0.66 (0.62–0.70)
	High continuity	0.24 (0.23–0.26)	0.33 (0.31–0.36)
Medium visit group (20–32 visits/year)
	Low continuity	1.00	1.00
	Medium continuity	0.57 (0.55–0.60)	0.66 (0.63–0.70)
	High continuity	0.26 (0.24–0.27)	0.34 (0.32–0.36)
High visit group (≥ 33 visits/year)
	Low continuity	1.00	1.00
	Medium continuity	0.57 (0.55–0.59)	0.62 (0.59–0.65)
	High continuity	0.28 (0.27–0.30)	0.36 (0.33–0.38)
