High-quality data on the potential impact of improving glycemic control is needed to inform the current recommendations to individualize HbA\n 1C<\/jats:sub>\n targets.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Data from 8 countries in the prospective cohort Peritoneal Dialysis Outcomes and Practice Patterns Study (2014\u20132022) were used to assess the association between baseline HbA\n 1C<\/jats:sub>\n and all-cause mortality in people with type 2 diabetes on PD for at least 90 days. Cox proportional hazards model adjusted for potential confounders was used to assess the relationship in the whole cohort and subgroups. Using inverse probability weighting, an average treatment effect in the treated analysis further investigated potential implications of improved glycemic control.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n HbA\n 1C<\/jats:sub>\n was measured at least once in 8436 patients during a mean follow-up of 16 months. Compared with HbA\n 1C<\/jats:sub>\n \u22648% (Diabetes Control and Complications Trial units), HbA\n 1C<\/jats:sub>\n >8% was associated with higher risk of all-cause mortality in the cohort as a whole (hazard ratio [HR] 1.18\n P<\/jats:italic>\n = 0.02 95% confidence interval [CI], 1.03 to 1.35) and within subgroups: age younger than 65 years (HR, 1.28;\n P<\/jats:italic>\n = 0.01; 95% CI, 1.05 to 1.56), average albumin >3.0 g\/dl (HR, 1.25;\n P<\/jats:italic>\n = 0.004; 95% CI, 1.07 to 1.46), no preexisting coronary artery disease (CAD; HR, 1.24;\n P<\/jats:italic>\n = 0.008; 95% CI, 1.06 to 1.46), hemoglobin <10 g\/L (HR, 1.50;\n P<\/jats:italic>\n = 0.01; 95% CI, 1.09 to 2.07), and PD vintage <1 year (HR, 1.22;\n P<\/jats:italic>\n = 0.02; 95% CI, 1.03 to 1.45). The projected survival advantage at 3 years for those with HbA\n 1C<\/jats:sub>\n \u22648% compared with >8% was 7% overall, increasing to 12% in younger cohorts (age younger than 65 years). The largest predicted absolute survival advantage of 16% (78% versus 61%) was seen in those aged younger than 65 years, with a normal serum albumin level and no history of CAD.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n Associations between HbA\n 1C<\/jats:sub>\n and mortality argue for tighter individualized targets for patient subgroups (younger, noninflamed, and without established CAD). Our weighted analysis suggests improved glycemic control (reducing HbA\n 1C<\/jats:sub>\n to <8%) may result in an absolute reduction in mortality at 3 years of up to 12% in younger cohorts.\n
