Regression models for inequalities in emergency admission rates controlled for primary care supply and quality 2004/2005–2011/2012 (n = 316 areas).

	Outcome: Absolute inequalities in emergency admissions (SII)		Outcome: Relative inequalities in emergency admissions (RII)

GPs per 100,000 patients (mean)	0.02 (0.007)*	0.01 (0.006)	0 (0.001)	0 (0.001)
