Colonic total and segmental transit times in healthy Italian adults.
Article in La Radiologia medica, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study was done to determine colonic transit times in healthy Italian adults. MATERIALS AND
methodsInstitutional review board approval and informed patient consent were obtained. Colonic segmental radiopaque markers were counted and transit times calculated in 36 healthy subjects studied using a technique involving daily radiopaque marker ingestion and single radiological visit, with oral administration of 8-10 ml of a thick barium paste as a colonic trace for the marker count. Two independent radiologists counted the marker twice. Observer agreement was assessed using comparison analysis.
resultsThere was very good observer agreement for the segmental marker counts. The upper limit for colonic transit times was: 45.6 h in the colon as a whole, 31.2 h in the right colon, 19.2 h in the left colon and 16.8 h in the rectosigmoid. Colonic transit times were not gender-related.
conclusionsIn healthy subjects, a barium trace affords optimal visibility of the different colonic segments, enabling accurate location of all markers and thus providing an anatomy-related, repeatable and reproducible fluoroscopic segmental marker count. We suggest that the reference values for normal colonic transit times could be adopted for Italian people irrespective of gender.
