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 platelet-to-lymphocyte ratio (PLR) is a useful predictive factor in several cancers. However, the prognostic value of PLR in patients with non-small-cell lung cancer (NSCLC) is still indistinct. Therefore, it was necessary for us to perform a meta-analysis to assess the prognostic value of PLR in patients with NSCLC.

methodsA systematic literature search was performed by using PubMed, EMBASE, and Web of Science databases for relevant studies until May 2015. Published studies investigating the association between PLR and overall survival (OS) and disease-free survival (DFS) were selected. Data from each eligible study were extracted. A meta-analysis was performed to analyze the prognostic value of PLR by using the hazard ratio (HR) and 95% confidence intervals (95% CI).

resultsA total of seven studies involving 1,554 patients were included in our meta-analysis. Our pooled results demonstrated that high PLR was associated with poor OS (HR: 1.60, 95% CI: 1.34-1.90, I (2)=22.3%, P heterogeneity = 0.259) and DFS (HR: 1.38, 95% CI: 1.11-1.73, I 2=0%, P heterogeneity = 0.482). Subgroup analysis between PLR and OS was performed in a further investigation. When the patients were segregated according to ethnicity, sample size, cutoff value, stage, and treatment modality, high PLR was also significantly correlated with OS. There was no significant heterogeneity among included studies.

conclusionHigh PLR is associated with poor prognosis in patients with NSCLC. PLR may be a significant predictive biomarker in patients with NSCLC.
