The association between amoxicillin administration and clinical outcomes in patients with AKI. (A) Association between amoxicillin administration and clinical outcomes. Four different methods were used to address the associations: 1) univariable Cox regression, 2) multivariable Cox regression, 3) propensity score matching, and 4) inverse propensity weighted modeling. (B) Kaplan‒Meier survival curves of the amoxicillin group and non-amoxicillin group after PSM for 30-day mortality. (C) Kaplan‒Meier survival curves of the amoxicillin group and non-amoxicillin group after PSM for 30-day mortality. Notes: HRs (95% CIs) were derived from Cox proportional hazards regression models. Covariates were adjusted as in the model II. The MDs (95% CIs) were derived from linear regression models. Covariates were adjusted as in the model II. Abbreviations: HR, hazard ratio; MD mean difference; PSM, propensity score matching; IPTW, inverse probability of treatment weighting; ICU, intensive care unit.
