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 prognostic role of neutrophil-to-lymphocyte ratio (NLR) in esophageal cancer (EC) remains controversial.

methodsThe aim of this study was to evaluate the association between NLR and oncologic outcome of EC patients through a meta-analysis. A systematic search was performed in PubMed, Web of Science and Embase for relevant studies. Meta-analysis was performed using hazard ratio (HR) and95% confidence interval (CI) as effect measures.

resultsFinally, 33 articles with 11,039patients were included in our study. The synthesized results indicated that the elevated NLR was negatively related to overall survival (OS) (HR = 1.39, 95% CI: 1.23-1.54). When the patients were stratified according to country, pathological type, treatment strategies, sample size, and different HR estimate method, high NLR was also significantly correlated with poor OS. Similarly, elevated NLR was also associated with shorter disease-free survival (DFS), progress-free survival (PFS), relapse-free survival (RFS), and cancer-specific survival (CSS).

conclusionThe elevated pretreatment NLR is associated with poor oncological outcomes in patients with EC. NLR may be a significant predictive biomarker in EC. Further large-cohort studies are needed to confirm these findings.
