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

introductionChronic subdural haematoma (CSDH) is a common neurosurgical condition in older adults, with a recurrence rate of approximately 7.1-13% after burr-hole drainage. Although surgical adjuncts such as subdural drains and middle meningeal artery embolisation may reduce recurrence, these are not suitable for all patients. Pharmacological strategies, including tranexamic acid, Goreisan and carbazochrome sodium sulfonate hydrate, have shown potential, but high-level evidence remains lacking. A prior retrospective study suggested that a triple oral regimen combining these agents may reduce recurrence. This randomised controlled trial aims to evaluate its efficacy and safety. METHODS AND ANALYSIS: This is a prospective, multicentre, open-label, randomised controlled trial conducted across six hospitals in Ibaraki, Japan. A total of 180 patients undergoing first-time burr-hole surgery for CSDH will be randomised 1:1 to receive either triple therapy (Goreisan 7.5 g/day, carbazochrome sodium sulfonate hydrate 90 mg/day and tranexamic acid 750 mg/day for up to 90 days) or standard postoperative care. The primary outcome is recurrence requiring reoperation within 90 days. Secondary outcomes include time to recurrence and haematoma volume reduction on serial CT imaging. All analyses will follow the intention-to-treat principle, using logistic regression, Cox proportional hazards models and mixed-effects models. ETHICS AND DISSEMINATION: Written, informed consent will be obtained from all participants at each participating hospital by trained staff from that hospital. The trial protocol has been approved by the ethics committee of the University of Tsukuba Hospital (approval no. TCRB23-025) and the Institutional Review Boards of all participating centres. Study findings will be disseminated through presentations at scientific conferences and publications in peer-reviewed journals. A summary of the results will also be provided to participating institutions and made publicly available in accordance with the TRIAL REGISTRATION NUMBER: jRCTs031240007.
