	Unemployed		Employed		PR (95% CI) for employed within strata of partners’ education
	N with/without outcome	PR (95% CI)	N with/without outcome	PR (95% CI)
Partner has less than secondary education	142/148	1.00 (Reference)	42/38	0.95 (0.74,1.22); p = 0.695	0.95 (0.74,1.22); p = 0.695
Partner has secondary or higher education	59/40	1.16 (0.94,1.43); p = 0.177	37/10	1.47 (1.17,1.84); p = 0.001	1.27 (1.02,1.57); p = 0.034

Measure of effect modification on additive scale: RERI (95% CI) = 0.36 (−0.02,0.71); p = 0.058
Measure of effect modification on multiplicative scale: ratio of PRs (95% CI) = 1.33 (0.96,1.83); p = 0.078
