Haemoglobin (Hb) variability has been reported to be associated with mortality in dialysis patients in some but not all studies. We aimed to establish the prognostic significance of Hb variability with all-cause mortality in haemodialysis patients through this meta-analysis.
The Medline, Embase, Cochrane Library and Web of Science databases were searched for studies assessing the association between Hb variability and all-cause mortality in haemodialysis patients after adjustment for other covariates.
We included three studies of five cohorts with a total of 262 641 patients. Forest plots showed that the combined hazard ratio for all-cause mortality was 1.09 (95% CI = 1.01-1.08; P = 0.03) per 1 g/dL increase in Hb variability.
Based on the current evidence, our meta-analysis found an association between Hb variability and all-cause mortality in patients receiving haemodialysis therapy.
血红蛋白(Hb)变异性已在一些研究中被报道与透析患者的死亡率相关,但并非所有研究都如此。本研究旨在通过荟萃分析确定 Hb 变异性与血液透析患者全因死亡率之间的预后意义。
检索 Medline、Embase、Cochrane 图书馆和 Web of Science 数据库,以评估调整其他协变量后 Hb 变异性与血液透析患者全因死亡率之间的相关性的研究。
共纳入三项研究,涉及五个队列,共 262641 名患者。森林图显示,Hb 变异性每增加 1g/dL,全因死亡率的综合危险比为 1.09(95%CI=1.01-1.08;P=0.03)。
基于目前的证据,我们的荟萃分析发现血液透析治疗患者的 Hb 变异性与全因死亡率之间存在关联。
