Univariable and multivariable logistic regressions predicting the likelihood of presence of musculoskeletal disorders and poor or average self-reported health rating based on PSS-4 and ERI values.

Outcome	Predictor variable	Univariable analysis			Multivariable analysis
		OR	95% CI	P	AOR	95% CI	P
MSD present	PSS-4	1.10	1.02-1.19	0.017	1.13	1.03-1.23	0.007
	ERI	1.56	1.05-2.32	0.027	1.56	0.99-2.45	0.056
Poor or average SRH	PSS-4	1.24	1.13-1.35	<0.001	1.30	1.17-1.45	0.001
	ERI	1.90	1.28-2.84	0.002	2.05	1.27-3.31	0.003

OR, odds ratio; AOR, adjusted odds ratio; CI, confidence interval; MSD, musculoskeletal disorder; SRH, self-reported health; PSS-4, perceived stress scale four items; ERI, effort-reward imbalance.
