Through reviewing previous literatures and assessing the confounding, the final regression models were adjusted for age [8–10], PD duration [10–13], comorbidity of diabetes mellitus [8, 13–16], serum albumin level [10,16], CRP level [17], fungal peritonitis [6,13,18], Gram-negative bacteria peritonitis [6,19], and multi-organism peritonitis [6,18–20]. The gene discussed is ALB; the disease is peritonitis.
