A new study published in Blood Purification aimed to clarify the association between folic acid FA supplementation and mortality in continuous ambulatory peritoneal dialysis CAPD patients. In this study overall 1 358 patients were classified by a cutoff value of FA . The association of FA with mortality was evaluated. The cutoff value of FA for predicting mortality was 34 at a median follow up of 40.7 months. The results revealed that FA 8805 34 was associated with decreased risk for all cause and cardiovascular mortality. Meanwhile the adjusted hazard ratios HRs per 10 higher FA for all cause and cardiovascular mortality were 0.925 and 0.926 respectively. Hence it was inferred that longer period of FA supplementation led to a reduction in risk of both all cause and cardiovascular mortality in CAPD patients.
