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 clinical impact of the platelet-to-lymphocyte ratio (PLR) on the prognosis of patients with metastatic renal cell carcinoma (mRCC) remains controversial. We investigated the associations between elevation of the PLR and disease prognosis in patients with synchronous mRCC. MATERIALS AND

methodsThe data of 1,505 patients with synchronous mRCC were retrospectively analyzed. The entire cohort was stratified into two subgroups according to PLR. Kaplan-Meier and Cox proportional analyses were performed to investigate the possible associations between the PLR and disease prognosis.

resultsThere were 921 patients with a high PLR and 584 patients with a low PLR by use of the cutoff of 146. The patients with a high PLR had worse clinical characteristics in terms of advanced clinical stage (p<0.001) and rate of lymph node invasion (p=0.036). The Kaplan-Meier analysis showed that patients with a high PLR had significantly shorter overall survival (OS) (p<0.001) and cancer-specific survival (CSS) (p<0.001). The multivariate Cox analysis revealed that the PLR was an independent predictor for shorter OS (hazard ratio [HR], 1.345; 95% confidence interval [CI], 1.183-1.530; p<0.001) and CSS (HR, 1.318; 95% CI, 1.156-1.502; p<0.001). In the subgroup analyses, the PLR showed a significant association with survival outcomes in the subgroup with clear cell type (all p<0.05) but not in the subgroup with the non-clear cell type.

conclusionsThe PLR was an independent prognostic factor for survival outcomes in patients with mRCC. However, the association was statistically significant only in patients with clear cell type mRCC.
