Figure 3 Events of severe complications for passive gravity vs negative pressure irrigation and sensitivity analysis results. Events of severe complications associated with different drain types are measured as those with a Clavien-Dindo grade ≥ IIIb. PG: Passive gravity; NPI: Negative pressure irrigation; Unadjusted: Univariate logistic regression model; Adjusted: Multivariate logistic regression model; PSM: Propensity score matching; CI: Confidence interval.
