Fig. 4From: Dealing with missing data in laboratory test results used as a baseline covariate: results of multi-hospital cohort studies utilizing a database system contributing to MID-NET® in JapanScenario2 (the risk of hepatic injury associated with rosuvastatin use compared to atorvastatin use). Hazard ratios from outcome models with and without baseline ALT, ALP, LDL-chol, or TG (SRI, MI, and IPW method were applied by hospital-specific-approach). Abbreviations: aHR, adjusted hazard ratio; ALT, alanine transaminase; ALP, alkaline phosphatase; CC, complete cases; CI, confidence interval; IPW, inverse probability weighted; LDL-chol, low-density lipoprotein cholesterol; MI, multiple imputation; TG, triglyceride; PS, propensity score; SRI, single regression imputation. † Not shown in the forest plot if the aHR is 8.0 or more. ‡The sample size in PS matching with MI gives the mean of 10 matched samplesBack to article page
