Effects of programmed death ligand 1 on the prognosis of neuroblastoma: A protocol for systematic review and meta analysis.
Article in Medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPrevious studies have investigated the prognostic role of programmed death ligand 1 (PD-L1) expression in patients with neuroblastoma, while the results are still controversial. Therefore, we conducted a meta-analysis to clarify the relationship between the expression of PD-L1 and the prognosis of neuroblastoma.
methodsSearch electronic databases include PubMed, Cochrane, Embase, Scopus and Web of Science, and the search time is set to build the database until January 2021. Hazard ratio (HR) and 95% confidence interval (CI) were used to analyze the included results. Meta-analysis was performed using Stata 15.0 software.
resultsThis review will be disseminated in print by peer-review.
conclusionThe study will provide updated evidence for the evaluation of whether the expression of PD-L1 is associated with poor prognosis in patients with neuroblastoma. ETHICS AND DISSEMINATION: The private information from individuals will not be published. This systematic review also should not damage participants' rights. Ethical approval is not available. The results may be published in a peer-reviewed journal or disseminated in relevant conferences. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/FBCY6.
