Risk factors for a composite outcome; multivariate generalized linear models (generalized estimating equation), adjusted by inverse propensity score weighting

Risk factor	Univariate analysis OR (95% CI)	Multivariate logistic regression analysis OR (95% CI)
Propensity score	–	0.33 (0.08–1.4)
Duration of treatment—long	1.42 (0.89–2.25)	1.66 (0.94–2.95)
Residency—home	0.62 (0.36–1.07)	0.67 (0.35–1.26)
Solid metastatic	2.35 (1.38–4.02)	2.5 (1.36–4.6)
Previous hospitalization	1.52 (0.95–2.43)	1.47 (0.86–2.5)
SOFA score	1.14 (1.05–1.23)	1.1 (1.01–1.2)
Nasogastric tube	2.26 (1.32–3.86)	2.11 (1.18–3.74)
Systolic blood pressure	1.14 (1.05–1.23)	0.99 (0.98–1.0)

N = 657, QIC 940.85, constant β = 0.043

As nasogastric tube and urinary catheter at presentation probably represent similarly baseline patient condition, only one was selected for multivariable analysis

Odds ratio > 1 correlates with higher risk for the composite outcome
