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
Background: Postoperative wound care is critical for recovery after discharge, but the COVID-19 pandemic limited access to follow-up. Mobile health applications may bridge this gap. This study evaluated the usability and acceptability of an app for postoperative wound monitoring. Methods: Patients undergoing hernia repair or abdominal surgery between 2020 and 2022 were enrolled. Through the app, patients uploaded wound images and received professional feedback. The study period was divided into non-COVID-19 and COVID-19 phases based on local outbreak severity. Usability was assessed by the System Usability Scale (SUS; score >68 considered usable). Acceptability was evaluated using the Net Promoter Score (NPS; range -100 to +100). Multivariable linear regression identified factors associated with SUS and NPS. Results: Sixty patients were included (mean age: 65.0 years; 53.3% male). Of these, 20 underwent hernia repair and 40 abdominal surgery; 31 were enrolled in the non-COVID-19 period and 29 in the COVID-19 period. Mean SUS and NPS were 79.6 ± 4.2 and 80.9 ± 3.8, respectively. Scores were higher during the COVID-19 period (SUS: 82.7 vs. 76.8; NPS: 83.4 vs. 78.5; both Conclusions: The app was highly usable and acceptable for postoperative wound care. Greater reliance on remote care during the pandemic and among rural patients was linked to higher scores. These findings support integrating digital health into surgical practice to improve access.
