[Meta-analysis of Platelet Lymphocyte Ratio as A Prognostic Factor for Non-small Cell Lung Cancer].
Synthesis in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundCurrent research shows that platelet to lymphocyte ratio (PLR) has important prognostic value in renal cell carcinoma, esophageal cancer, gastric cancer, liver cancer and colon cancer. The aim of the study is to evaluate the prognostic value of PLR in non-small cell lung cancer (NSCLC) through meta-analysis.
methodsLiterature search for PubMed, EMBASE, Web of Science, Medline, Cochrane Library, China National Knowledge Internet (CNKI), China Biomedical Medicine disc (CBMdisc), VIP, Wanfang Database using computer electronic system to study the association between PLR and overall survival (OS) and disease-free survival (DFS). Each eligible study data is extracted and a meta-analysis is performed using the hazard risk (HR) and 95% confidence interval (95%CI) to assess the prognostic value of PLR, the time limit for the search is to build the library until November 2018.
resultsWe include a total of 15 research literatures involving 5,524 patients for meta-analysis. According to the results of the meta-analysis: The OS of the higher PLR group is significantly lower than that of the lower PLR group (HR=1.69, 95%CI: 1.45-1.97, P<0.000,01, I²=46.2%, Pheterogeneity=0.026); the DFS of the higher PLR group is significantly lower than that of the lower PLR group (HR=1.41, 95%CI: 1.14-1.74, P=0.001, I²=46.2%, Pheterogeneity=0.026). Subgroup analysis show that the OS of the higher PLR group is still significantly lower than the lower PLR group (P<0.05) after grouping by ethnicity, sample size, PLR cutoff value and treatment.
conclusionsIncreased PLR is associated with poor prognosis in NSCLC, so PLR may be an important biological predictive marker for NSCLC patients, however, its clinical application still needs to be verified through more research in the future.
