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

backgroundThe aim of this study was to systematically evaluate the prognostic role of platelet lymphocyte ratio (PLR) in patients with melanoma through performing a meta-analysis.

methodsPubMed, EMBASE, Web of Science, and China National Knowledge Infrastructure were searched for potential studies. The basic characteristics and relevant data were extracted. Hazard ratios with 95% confidence intervals (CIs) were pooled to evaluate the prognostic role of PLR in patients with melanoma.

resultsTen studies enrolling 2422 patients were included. The pooled hazard ratios of higher PLR for overall survival and progression-free survival in melanoma were 1.70 (95% CI, 1.22-2.37) and 1.65 (95% CI, 1.10-2.47), respectively. Sensitivity analysis and subgroup analyses were also performed. No significant publication bias was observed.

conclusionOur results showed that higher PLR was associated with poorer overall survival and progression-free survival in patients with melanoma. These findings may help to determine the prognosis and explore future novel therapies based on modulating inflammation and immune responses in melanoma.
