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

purposeThe neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios have been proposed as emerging markers of inflammation and prognosis in maintenance hemodialysis (MHD) patients. However, to date, no longitudinal performance of these indices is known. The study's purpose was to examine the longitudinal relationship between NLR, PLR, inflammatory and nutritional parameters in MHD patients and how their changes over time associate with adverse clinical outcomes.

methodsA historical longitudinal cohort study was conducted using a clinical database which included 554 patients (mean age, 67.6 ± 14.2 years; 34% women) from a single center receiving MHD from November 2007 to July 2018. NLR, PLR, C-reactive protein (CRP) and nutritional parameters were recorded at 0, 6, 12, 18, 24, 30 and 36 months, followed by 58 additional months of clinical observations.

resultsIn a linear mixed-effects model adjusted for baseline demographics and clinical parameters, including white blood cell count, NLR and PLR were both associated with CRP levels at any given time point observation (linear estimates (95% CI): 1.53, (0.11-2.95) and 1.55 (0.15-2.93), respectively). For each 1.0-unit increase in NLR over time, the fully adjusted all-cause mortality hazard ratio using Cox models with the time-varying risk effect was 1.04 (95% CI 1.01-1.07, P = 0.006). However, when CRP was included in this model, the relationship was no longer significant. PLR's performance did not match the prognostic marker.

conclusionLongitudinal changes in NLR mimic CRP changes and predict all-cause mortality risk in MHD patients.
