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
Introduction: Osteoporotic vertebral fractures (OVFs) are the most common type of fragility fracture in elderly patients with osteoporosis. Bracing is widely used for conservative treatment; however, few studies have objectively assessed patient adherence to prescribed brace usage. This prospective study aimed to evaluate true patient compliance with the Jewett brace for acute OVFs using a temperature logger embedded in the brace. Methods: Patients aged ≥65 years with an acute OVF diagnosed within two weeks of injury were enrolled between February 2024 and January 2025. After two weeks of bed rest, patients began ambulation while wearing a Jewett brace. A button-type temperature logger was installed on the sternal pad of the brace to record the temperature every 30 minutes for 42 consecutive days. Wearing was defined as temperatures ≥30°C. Based on previous reports, wearing the brace for 15 hours daily was defined as 100% compliance. Compliance was calculated for the entire period, for hospitalization versus post-discharge, and at three 14-day intervals. Correlations between vertebral instability and compliance were also analyzed. Results: A total of 17 patients were included in the final analysis. The mean overall compliance rate was 85.8%, corresponding to an average wearing time of 12.9 hours per day. Brace compliance was consistently maintained at a high level during hospitalization and after discharge, as well as across the first, second, and last 14-day intervals. The daily wearing rate peaked at approximately 80% around mealtimes and remained above 70% during daytime hours. A significant, moderately positive correlation was observed between vertebral instability and compliance in the last 14 days. Conclusions: This study objectively demonstrated a remarkably high patient compliance rate of 85.8% (12.9 hours per day) with Jewett braces for OVFs during the 42-day period following the initial two-week hospitalized bed rest.
