The evaluation of postoperative bowel dysfunction in Japanese patients with rectal cancer.

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
purposeThe present study assessed postoperative bowel dysfunction in Japanese patients with rectal cancer, including patients who underwent preoperative radiotherapy (RT).
methodsA total of 277 rectal cancer patients who underwent primary resection were included in the analyses. A questionnaire survey was administered using the low anterior resection syndrome (LARS) score and Wexner score. Scores were determined one year after rectal surgery or diverting ileostomy closure. The LARS score was categorized as minor LARS (21-29) and major LARS (30-42).
resultsThe proportions of patients with minor and major LARS were significantly larger and Wexner scores significantly higher in patients with distal tumors and a lower anastomosis level than in those with proximal tumors and a higher anastomosis level. Among the patients with lower rectal cancer, the proportions with minor and major LARS were similar between those with and without preoperative RT. The Wexner scores in patients with preoperative RT were significantly higher than in patients without RT. A distal tumor location and lower anastomosis level were independent risk factors of major LARS in multivariate analyses.
conclusionA distal tumor location, low anastomosis level, and preoperative RT might be associated with postoperative bowel dysfunction in rectal cancer patients.
