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

introductionNew evidence suggests that the ratio of neutrophils to lymphocytes is associated with the prognosis of other carcinoma, but the ratio of neutrophils to lymphocytes in laryngeal squamous cell carcinoma remains controversial.

objectiveThe objective of this meta-analysis was to clarify the prognostic effectiveness of the ratio of neutrophils to lymphocytes in laryngeal squamous cell carcinoma.

methodsAccording to the meta-analysis of the free guide, we searched EMBASE, Pubmed, the Cochrane Library databases. The ratio of neutrophils to lymphocytes of laryngeal squamous cell carcinoma patients was evaluated using mean standard vehicle and confidence interval. The overall survival, disease-free survival and progression free survival of patients with laryngeal squamous cell carcinoma were expressed by standard mean carrier method and confidence interval. The risk ratio of 95% confidence interval was used as an evaluation index for patients with laryngeal squamous cell carcinoma.

resultsEight studies, including 1780 patients, used a variety of different end values to classify the ratio of neutrophils to lymphocytes (range 1.78-4.0). Among the eight studies that reported risk ratio of the overall survival, the higher median value was 2.72, and 2 of 4 studies reported disease-free survival results. The critical value of ratio of neutrophils to lymphocytes and overall survival deterioration (risk ratio = 1.68, 95% confidence interval 1.43-1.99, p < 0.001), disease-free survival (risk ratio = 2.09, 95% confidence interval 1.62-2.6, p < 0.001) and progression free survival (risk ratio = 1.92, 95% confidence interval 1.75-2.10, p < 0.001) was associated with with laryngeal aquamous cell carcinoma. The ratio of neutrophils to lymphocytes had prognostic value for laryngeal squamous cell carcinoma.

conclusionThe results of this meta-analysis showed that the increase of neutrophils to lymphocytes ratio was related to poor prognosis of laryngeal squamous cell carcinoma. The neutrophils to lymphocytes ratio may serve as a cost-effective prognostic biomarker of poor prognosis of laryngeal squamous cell carcinoma. More high-quality prospective trials are needed to assess the practicability of evaluating the ratio of neutrophils to lymphocytes in laryngeal squamous cell carcinoma.
