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

backgroundPharmacologic treatment of vestibular schwannomas (VSs) may increase the success of conservative management for small lesions, and offer an alternative to surgery and stereotactic radiotherapy in symptomatic cases in the high-risk population. Agents that have been studied include aspirin (ASA), but the results of the preliminary studies have been conflicting. In this study, we aimed to systematically review the evidence on the effect of ASA intake on tumor growth in patients with VSs.

methodsPubmed, Cochrane, Scopus, Embase, ClinicalTrials.gov , and Web of Science were searched for studies comparing VS tumor growth in patients with aspirin intake and those without. Random-effect meta-analysis was used to evaluate the outcomes in terms of linear and/or volumetric tumor growth.

resultsFour retrospective cohort studies were included in the meta-analysis. No significant difference was found in tumor growth between VS patients with aspirin intake and those without. This result held true for the analysis of linear tumor growth (OR 1.23; 95% CI 0.49, 3.10), volumetric tumor growth (OR 1.41; 95% CI 0.36, 5.59), and both combined (OR 1.02; 95% CI 0.56, 1.86).

conclusionsOur meta-analysis suggests that there is insufficient evidence to recommend ASA therapy in patients with VSs. High-quality randomized controlled trials are warranted to determine the efficacy of this drug in reducing VS tumor growth.
