The potential confounding bias for interested outcomes was controlled by the propensity score weighting (PSW)and calculated the adjusted odds ratios.The confounding factors includedage, sex, Elixhauser comorbidity score, income, region, obesity, tobacco use, diabetes, coronary artery disease, chronic kidney disease, and chronic anemia.
