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
Minimally invasive esophagectomy is the preferred treatment for esophageal cancer. However, postoperative opioid analgesics are commonly used, and a nasogastric tube (NGT) is usually retained after surgery. There are few studies on the correlation between postoperative NGT retention duration and total postoperative opioid consumption. This study investigates the correlation between postoperative opioid consumption and NGT retention duration in patients undergoing minimally invasive esophagectomy. This single-center retrospective cohort study collected data from patients with esophageal cancer who underwent minimally invasive esophagectomy at the Department of Cardiothoracic Surgery, Affiliated Hospital of Putian University from January 2020 to December 2024. A total of 168 patients were included and divided into groups based on whether the NGT retention duration exceeded 7 days. The total postoperative opioid consumption was calculated and converted to daily oral morphine equivalent doses. Univariate analysis showed that postoperative hospital stay, NGT retention duration, fasting days, ICU stay, and postoperative complication grade were significantly correlated with postoperative morphine dose. Multivariate linear regression analysis showed that compared with the group with NGT retention duration ≤ 7 days, the group with NGT retention duration > 7 days had an average increase of 77.13 mg in postoperative morphine consumption (95% confidence interval: 31.62-122.65, P = .001). After adjusting for all covariates, the β value and 95% CI were 52.71 (3.84-101.59). Subgroup analysis and curve fitting results showed a significant linear positive correlation between NGT retention duration and total postoperative morphine consumption (P for overall = .001). There is a significant linear positive correlation between postoperative opioid consumption and NGT retention duration in patients undergoing minimally invasive esophagectomy. Clinicians should pay attention to the impact of NGT retention duration on postoperative pain. By optimizing postoperative management strategies and reducing unnecessary NGT retention duration, the quality of postoperative recovery can be improved.
