Colorectal dimensions in the general population: impact of age and gender.
Article in Surgical and radiologic anatomy : SRA, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeConstipation is among the most common gastrointestinal disorders, although, there is no generally accepted objective diagnostic criteria thereof. It has been proposed that colorectal dimensions assessed with Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) may support the diagnosis, but normative data are lacking. The aim of this study was to describe colorectal dimensions in a sample of the general population and to investigate whether the dimensions were under influence by age and gender.
methodsThe maximum diameters and cross-sectional areas of the ascending colon, descending colon and rectum were determined from 119 CT scans of trauma patients (age groups from 15 to 70 years, 84 men and 35 women). A regression model was applied to explore the impact of age and gender on colorectal dimensions.
resultsOverall, great variations were found for all colorectal diameters and cross-sectional areas (median diameter (5% percentiles; 95% percentiles): ascending 46 (26; 63) mm; descending 29 (16; 48) mm; rectum 39 (22; 67) mm. Women had larger rectal cross-sectional areas, reflecting more rectal content, compared to men (p = 0.003). Age did not affect colorectal diameters or cross-sectional areas (all p > 0.10).
conclusionGreat variations of colorectal dimensions were found. Larger rectal cross-sectional areas in women could likely reflect the fact that women have increased prevalence of constipation. Future studies should take gender into consideration when evaluating colorectal dimensions.
