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
BACKGROUND/
aimsSigmoidoscopy is performed in most medical centers to evaluate the distal colons of young adults presenting with hematochezia who are at risk of developing proximal lesions. Colonoscopies offer more complete evaluations but are associated with a higher incidence of complications and possible low yield.
methodsAn analysis was conducted on colonoscopies performed in our center on patients 40 years of age or younger. The study population was sub-divided into 2 age groups for analysis: <30 years of age and 30-39 years of age.
resultsWe recruited 453 patients for the study. Patients were 115 and 338 individuals that were <30 and 30-39 years of age, respectively. Hemorrhoids was identified as the cause of bleeding in the majority of cases. The overall incidence of polyps was 6.5%; this was significantly higher in the 30-39 age group (7.4% vs. 1.7%, p=0.026). There were two cases of advanced/malignant polyps. While the majority of the polyps were in the distal colon, 28% of the polyps in the older age group were found in the proximal colon. There was one case of colonic perforation.
conclusionColonic polyps are more prevalent in patients aged 30-39. Colonoscopies should be considered for patients over the age of 30 with rectal bleeding.
