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

introductionTakotsubo syndrome (TTS) is a sudden reversible weakening of the left ventricle function induced by severe stress and resembles many features as acute coronary syndrome. Even though many guidelines had been published about TTS, there is no consensus regarding the long-term treatment. Aspirin is one of the most common prescribed medicines at discharge for patients with the intention to reduce thrombus events and improve the overall prognosis. However, existing studies yielded conflicting results concerning its effects. This study aims to evaluate the impact of long-term maintenance treatment of aspirin in TTS and provides insights in clinical management. METHODS AND ANALYSIS: After searching through electronic databases (PubMed, Embase, Cochrane Library, Web of Science, National Library of Medicine Gateway, CNKI, Wanfang and VIP), grey literatures, conference abstract and trial registries for clinical studies investigating the impact of aspirin on patients with TTS, a systemic review and meta-analysis will be conducted. The search will be limited from inception of each database to 1 August 2020. The outcomes including all-cause death, TTS recurrence, stroke, transient ischaemic attack or myocardial infarction at 30-day and 5-year follow-up will be examined. Risk of bias will be assessed by Newcastle-Ottawa quality assessment scale for observational studies and Cochrane Effective Practice and Organization of Care evaluation tool for interventional studies. Grading of Recommendations Assessment, Development and Evaluations method will be applied to assess the quality of evidence. If available, the effects of aspirin on the above outcomes for patients with TTS will be evaluated using random-effect modelling with relative risk at 95% CIs. Subgroup analysis and sensitivity analysis will also be performed when possible. ETHICS AND DISSEMINATION: Ethics approval was not required due to the retrospective nature of the study. Results of the review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42020212729.
