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 and Aim: Sarcopenia is commonly observed in patients with periampullary cancer. Even in early-stage cases, it is associated with higher morbidity and poor postoperative outcomes. In this study, we aimed to evaluate the impact of sarcopenia on overall survival in patients with resectable periampullary cancer. Methods: We retrospectively analyzed data from all patients with resectable periampullary cancer who met the inclusion criteria and underwent curative surgery at Songklanagarind Hospital between 2013 and 2023. All eligible patients had preoperative abdominal computed tomography scans, and we calculated the skeletal muscle index (SMI) at the L3 vertebral level. Patients were categorized into sarcopenia and non-sarcopenia groups based on SMI thresholds. We compared baseline characteristics, laboratory parameters, and overall survival using Kaplan-Meier analysis. Results: A total of 139 patients were included, with 71 in the sarcopenia group and 68 in the non-sarcopenia group. Patients with sarcopenia were older (66.1 ± 10 vs. 60.2 ± 11 years, Conclusion: Preoperative sarcopenia is a key negative prognostic factor for overall survival and postoperative outcomes in patients with resectable periampullary cancer. Enhancing postoperative SMI through exercise and nutritional intervention should be integrated in postoperative care to improve survival outcomes in this population.
