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

purposePrehabilitation is known to improve outcomes of gastrointestinal surgery; however, the issue of low adherence during the waiting period for surgery remains unresolved. This study evaluated the effectiveness and feasibility of a newly developed mobile health application, "Preha," designed to support home-based prehabilitation.

methodsA single-group pilot study involving patients scheduled for major hepatobiliary-pancreatic (HBP) surgery for malignancy between March 2023 and September 2024 was conducted. The patients downloaded the Preha application, and there was no direct intervention from the medical staff during the preoperative period. The application recorded step counts, moderate-intensity exercise times, and squat counts. Adherence was defined as meeting at least one of the following: ≥ 5,000 steps/day, ≥ 10 min/day of ≥ 3 METS activities, or ≥ 30 squats/day, for more than three days per week.

resultsAmong 30 eligible patients, 21 (median age, 67 years) were included in the analysis. During prehabilitation, 52% achieved the step goal, 67% met the exercise time target, and 33% completed the squat goal.

conclusionsThe "Preha" application facilitated good adherence to home-based prehabilitation without direct intervention, indicating its feasibility and potential as a perioperative support tool for patients undergoing HBP surgery.
