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
Aims: Gastric emptying dysfunction is a major concern after gastrectomy for gastric cancer; however, its long-term course and relationship with surgical procedures remain unclear. This study aimed to evaluate gastric emptying function longitudinally over 12 months postoperatively using the Methods: A prospective cohort of 95 patients who underwent curative gastrectomy for gastric cancer between April 2021 and July 2024 was assessed. A novel semi-solid test meal, integrated with a Results: The median T1/2 was 42.0 min preoperatively, delayed to 45.9 min at 1 month, and then significantly decreased to 23.4 min at 6 months and 18.7 min at 12 months postoperatively. In distal gastrectomy with Billroth I or Roux-en-Y reconstruction, T1/2 was prolonged at 1 month but improved markedly at 6 and 12 months. In contrast, proximal gastrectomy with modified side-overlap esophagogastrostomy and total gastrectomy showed consistently rapid gastric emptying at all time points. Conclusion: Gastric emptying function after gastrectomy demonstrated dynamic, time-dependent changes, with an initial postoperative delay followed by significant acceleration within the first year. The pattern and degree of change differ depending on the surgical procedure and reconstruction method. These findings highlight the importance of individualized, and time-adapted nutritional management after surgery in patients with gastric cancer.
