This study provided results that are similar to study by Chen dkk, 2011, in which
combination of HD + HP improved quality of life and hope of life parameters of regular
hemodialysis patients. There are also 16 other studies with similar meta-analysis
characteristics preceding our studies that provided insignificant result in cardiovascular
mortality and overall mortality between hemodiafiltration (HDF), hemofiltration (HP) and
conventional hemodialysis (HD). However, significant decrease in β2-microglobulin
concentration is only found in HP modality (Wang et al 2014).
