The Value of Colonoscopy in Assessing Rectal Bleeding in Patients Referred From Outpatient Care Units in Erbil, Iraq.

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 AND
objectivesRectal bleeding denotes bleeding from the lower colon or rectum, specifically from a location distal to the ligament of Treitz. Lower gastrointestinal bleeding (LGIB) is very common in adults of all ages. This study aimed to review the diagnostic findings of colonoscopy in outpatients who had nonurgent rectal bleeding and identify common pathologies causing rectal bleeding in patients at Erbil and Rizgary Teaching Hospitals in Iraq.
methodsWe selected 400 male and female patients from outpatient departments with evidence of rectal bleeding, referring them to the gastroenterology units of Erbil and Rizgary Hospitals in Erbil, Iraq. Patients with upper gastrointestinal bleeding (UGIB) sources and other symptoms were excluded from the study. We prepared the bowel, subjected all patients to a colonoscopy, and recorded the findings. Where necessary, biopsies were also taken. A diagnosis was made based on the colonoscopic findings.
resultsThe total number of patients was 400. Their mean age + SD was 44.9 + 15.9 years, ranging from 18 to 83 years, and the highest proportion of the diagnoses was hemorrhoids, either alone (n = 140, 35%) or in combination with other diseases. The results indicated that 48 (40%) males aged < 45 years had hemorrhoids, compared with 33 (33.7%) males aged ≥ 45 years; for females, 29 (30.9%) in those aged < 45, compared to 30 (34.1%) in those aged ≥ 45. The next two prevalent diagnoses in the total sample were inflammatory bowel disease (n = 31, 7.8%) and colorectal tumor (n = 37, 9.3%). It was observed that around one-fifth (n = 79, 19.8%) of the sample was normal.
conclusionThis study highlights the leading causes of LGIB as diagnosed through colonoscopy. The main causes and patterns of LGIB across gender and age groups in Erbil were generally similar to other settings but with some differences. Hemorrhoids caused the most rectal bleeding, followed by tumors and then inflammatory bowel disease. The older group had more cases of diverticulosis than the younger group. Although most findings were benign, colonoscopy should be strongly considered for outpatients (young and old) with nonurgent rectal bleeding.
