1 · What the graph read from it

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.

2 · The registry

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/

aimsThe length of colon is known to be longer in females than in males. In addition, the morphology of colon cancer is different between males and females. The aim of this study was to investigate sex differences in Boston bowel preparation score (BBPS) and colonoscopy insertion time.

methodsThis study retrospectively analyzed medical records and colonoscopy readings of subjects who underwent colonoscopy at Seoul National University Bundang Hospital from March 2015 to April 2018. BPPS was used to evaluate the degree of colon cleanness before colonoscopy. Statistical analysis was performed to compare demographic, clinical, and outcome variables between two groups.

resultsThe study group consisted of a total of 12,561 patients (6,148 females and 6,413 males). Mean age was 57.8 ± 13.5 years for females and 57.5 ± 13.8 years for males (p = 0.695). Females showed better bowel preparation than males (mean total score: 7.4 ± 1.8 vs. 7.2 ± 1.9, p = 0.001; total score ≥ 6: 5,340 [86.9%] vs. 5,437 [84.8%], p = 0.001; BBPS ≥ 2 for all segments: 5,048 [82.1%] vs. 5,097 [79.5%], p < 0.001). However, cecal intubation time (8.3 ± 6.2 minutes vs. 6.2 ± 6.1 minutes, p < 0.001) and withdrawal time (7.9 ± 3.5 minutes vs. 7.4 ± 3.1 minutes, p < 0.001) were longer in males.

conclusionThere were sex differences in BBPS, cecal intubation time, and withdrawal time for subjects undergoing colonoscopy.
