Defecation delay in patients after lung tumor surgery: a prospective nested case-control study.

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
backgroundDefecation delay (greater than or equal to 3 days post-surgery) is a common symptom in patients after lung tumor surgery. This study investigated the incidence and relevant risk factors of defecation delay in patients after lung tumor surgery.
methodsBetween October 2019 and March 2020, a prospective nested case-control study was conducted in 80 patients who received lung tumor surgery in the Department of Thoracic Surgery at the Sun Yat-sen University Cancer Center. According to the Rome III criteria for functional constipation and the accepted definitions in the literature, patients with defecation delay time greater than or equal to 3 days post-surgery were classified as the defecation delay group, and the remaining patients were considered the control group. A questionnaire survey was conducted to explore the trait of the stool, defecation time, postoperative activity, diet, and perioperative pain score. Statistical analyses were performed to compare the risk factors affecting defecation time in the two groups.
resultsOut of 80 patients, a total of 44 patients (44/80) experienced defecation delay after the operation. Univariate analysis showed that there were significant differences between the two groups in operation methods (P<0.029), postoperative stool trait (P<0.001), difficulty in defecation (P<0.01), and perioperative pain score (P=0.0178), suggesting that change of stool characteristics and pain were possible factors causing defecation delay. Multivariate analysis also revealed significant differences between the two groups in the postoperative pain score on the first day post-surgery (P=0.03).
conclusionsDefecation delay is a common symptom in patients after lung cancer surgery, and is related to operation method, pain score, and changes in stool characteristics. This study identified that minimally invasive surgery, postoperative pain relief treatment, and health education may play an important role in preventing delayed defecation.
