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
purposeTo explore the expression of tumoral Gal-1 in association with clinical parameters and outcome in a large population with laryngeal squamous cell carcinomas (LSCCs).
methodsA total of 187 patients with LSCC were retrospectively enrolled. Immunohistochemistry was performed to evaluate the tumoral expression of Gal-1, apoptosis-related proteins and the density of tumor infiltrating lymphocytes (TILs) in tumor tissues before any intervene. Survival curves were estimated by the Kaplan-Meier method, and differences in survival between groups were determined using the log-rank test. Prognostic effects were evaluated by Cox regression analysis.
resultsA total of 102 carcinomas (54.5 %) were identified as high Gal-1 expression, and 85 carcinomas (45.5 %) as low expression. Tumoral Gal-1 expression was not significantly related with clinical stage and histology differentiation. No correlation of Gal-1 expression with apoptosis-related protein was identified. Instead, Gal-1 status was correlated positively with the ratio of FOXP3(+)/CD8(+) TILs (P = 0.024). In multivariate regression analysis, advanced clinical stage and the presence of metastases were identified as the independent predictors for poor survival in entire cohort. Especially, the statistical correlation between the Gal-1 expression and prognosis was particularly due to the late-stage tumors (P < 0.05).
conclusionCurrent results represent valuable advancements in Gal-1 research and provided further support for using Gal-1 as a diagnostic biomarker and immunotherapeutic target for LSCC.
