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 objective: Early nutritional support holds paramount importance for postoperative gastric cancer (GC) patients. Peptidase M20 domain containing 1 (PM20D1) is a secretory enzyme associated with glucose and lipid metabolism. However, there is a dearth of clinical studies delving into the connection between PM20D1, lipid metabolism, and inflammatory factors in GC patients who have received enteral nutrition (EN). This research aimed to investigate the serum levels of PM20D1 in GC patients following early EN and their potential associations with lipid metabolism, nutritional markers, and inflammatory factors. Methods: This prospective observational study enrolled 180 GC patients between May 2020 and July 2022. On the first postoperative day, all patients received EN support, which was maintained for a duration of 5 days. Serum levels of PM20D1, interleukin (IL)-6, IL-1β, and C-reactive protein were measured on the sixth day after surgery using an enzyme-linked immunosorbent assay. Data on demographics, clinical statistics, lipid metabolism, nutritional parameters, and the prognostic nutritional index (PNI) were collected. Patients were followed up for 12 months, and both overall survival and disease-free survival were recorded. Results: In the low PNI group, the serum levels of PM20D1, albumin (ALB), and blood lymphocytes (BL) showed significant reductions. Pearson analysis revealed a negative correlation between PM20D1 and IL-6 levels, whereas a positive correlation emerged between PM20D1 and ALB and BL levels. Furthermore, PM20D1 demonstrated potential as a biomarker for diagnosing poor nutritional status (PNI < 43) in GC patients and was a risk factor for poor nutritional status in GC patients. Conclusion: Serum PM20D1 remarkably declined in GC patients after early EN and was associated with poor nutritional status.
