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

introductionPeriodontitis and chronic kidney disease (CKD) are inter-related conditions that can significantly impact patient health. This study aims to evaluate the efficacy of active non-surgical periodontal therapy (NSPT) combined with supportive periodontal care (SPC) in reducing tooth loss and improving masticatory function in patients with CKD and stage III periodontitis. METHODS AND ANALYSIS: This randomised controlled trial will recruit 86 patients diagnosed with both stage III periodontitis and CKD. Participants will be randomly assigned at a 1:1 ratio to either an experimental group receiving active NSPT supplemented with SPC or a control group receiving oral hygiene instruction with scheduled periodontal monitoring. The intervention will last for 24 months, with assessments conducted at baseline and 3, 6, 12, 18 and 24 months. The primary outcome is the incidence of tooth loss due to periodontitis over the 2-year follow-up period. Secondary outcomes include the number of lost teeth, masticatory function, clinical periodontal parameters and oral health-related quality of life. ETHICS AND DISSEMINATION: The study protocol and informed consent form were approved by the Institutional Ethics Committee of Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine (SH9H-2022-T404-1). Findings will be disseminated to participants and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ChiCTR2300068923.
