1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

<p>Introduction: In contrast to high-flux dialysis (HFD) membranes, medium cut-off membranes (MCO) can potentially remove a wide range of middle molecules. Our study aimed to compare the clearance rate (CR) of fibroblast growth factor 23 (FGF-23) and other selected inflammatory cytokines between medium MCO and HFD membranes and investigate the intrasubject stability of these biomarkers.

methodsThis prospective randomised case-crossover study recruited 20 adult patients who were randomised into two groups: group A: to start with 1 week of thrice-weekly dialysis using HFD membrane followed by a 3-week washout period and then 1 week of dialysis with an MCO membrane. Group B followed the reverse sequence. Blood samples were taken before and after each dialysis session for the analysis of the assessed biomarkers (FGF-23, interleukin-6 [IL-6], interleukin-18 [IL-18], high-sensitivity C-reactive protein [hsCRP], and dephosphorylated uncarboxylated matrix Gla protein [dp-ucMGP]). Wilcoxon signed rank and paired t tests were used for comparison between the membranes. One-way repeated measures ANOVA or Friedman tests were used for the intrasubject stability of the biomarkers.

resultsThe use of both MCO and HFD membranes resulted in a significant reduction of FGF-23 levels and other selected inflammatory cytokines. However, there was no significant difference in the CR: FGF-23 (0.31 vs. 0.23], p = 0.242), IL-6 (0.19 vs. 0.12, p = 0.215), IL-18 (-0.05 vs. -0.03, p = 0.704), dp-ucMGP (0.33 vs. 0.33, p = 0.903), and hsCRP (-0.05 vs. -0.08, p = 0.107). There was no significant intrasubject variability for all assessed biomarkers except in pre-dialysis high hsCRP levels when using HFD membrane.

conclusionThe use of both MCO and HFD membranes resulted in a significant reduction of FGF-23 levels and other selected inflammatory cytokines. However, the MCO membrane did not demonstrate a significant advantage over the HFD in the short term. There was no significant intrasubject variability for all assessed biomarkers apart from hsCRP. </p>.
