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

backgroundRed blood cell distribution width to platelet count ratio (RPR) has garnered increasing attention as a novel inflammation marker. However, its association with cardiovascular events (CVE) in end-stage renal disease patients undergoing peritoneal dialysis (PD) is largely unknown.

method1,222 PD patients, from 4 centers, were retrospectively recruited between January 1, 2012-December 31, 2017. Baseline data were collected ~ 3 months after starting PD treatment, and patients divided into 2 groups (low RPR [n = 710], high RPR [n = 512]), based on the optimal RPR cut-off of 0.084 identified by receiver operating characteristic curve analysis. The relationship between RPR with new CVE, cardiovascular disease mortality, and all-cause mortality was analyzed using restricted cubic spline (RCS) and Kaplan-Meier survival curve analyses. Associations between RPR and patient characteristics were identified using uni- and multi-variate Cox logistic regression analyses, adjusted for baseline patient characteristics, co-morbidities, and laboratory parameters. Competitive risk analysis was conducted to assess the effects of other follow-up endpoint events on CVEs.

results77 new CVEs and 212 deaths occurred during the follow-up period. High RPR, versus low, had significantly higher rates of new CVEs under Kaplan-Meier analysis; this was still present even after adjusting for specific baseline characteristics, co-morbidities, and laboratory parameters under multivariate Cox regression analysis. RCS analysis also revealed that the relationship between RPR and CVE was non-linear, with RPR ~ 0.06-0.15 being associated with higher CVE risk.

conclusionHigher RPR may serve as an independent prognostic marker for CVE risk in PD patients, providing a non-invasive, cost-effective marker for early CVE detection.
