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 significance of Neutrophil-to-Lymphocyte Ratio (NLR) and Platelet-to-Lymphocyte Ratio (PLR) in Small Cell Lung Cancer (SCLC) patients receiving platinum-based chemotherapy is debated.

methodsThis study aims to elucidate their roles in survival outcomes. A systematic search across PubMed, Embase, Web of Science, and Cochrane Library identified relevant studies. The Newcastle-Ottawa Scale (NOS) evaluated study quality. Meta-analysis was conducted using random-effects and fixed-effects models, supplemented by sensitivity analysis.

resultsA total of 11 studies with 3,634 SCLC patients were included. Patients with high NLR had significantly decreased overall survival (OS) (HR = 1.39, 95% CI: 1.18-1.59, P < 0.001) and progression-free survival (PFS) (HR = 1.52, 95%CI: 1.27-1.78, P < 0.001). The OS was not statistically different between high and low PLR groups (HR = 1.13, 95%CI: 0.84-1.43, P = 0.265). Subgroup analysis revealed that OS in high NLR group was significantly lower across different strata, and OS in the high PLR group was significantly lower among patients with limited-stage SCLC (LS-SCLC) and populations with a PLR cutoff value < 160.

conclusionsHigh NLR is associated with poor OS and PFS in patients with SCLC receiving first-line platinum-based chemotherapy. PLR does not significantly impact OS, except in LS-SCLC patients and populations with a PLR cutoff value < 160. These findings require further validation from prospective studies.
