MACROSCOPIC AND HISTOLOGICAL ANALYSIS ON ENDOSCOPICALLY RESECTED RECTAL LESIONS.
Observational study in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery, 2023. 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
backgroundColorectal cancer is among the most common malignancies worldwide. Colonoscopy is the examination of choice for the prevention of CRC because of its great diagnostic and, especially, therapeutic capacity in relation to adenomatous lesions.
aimsThis study aimed to analyze the prevalence, macroscopic, and histological characteristics of polypoid rectal lesions resected through endoscopic techniques and assess whether endoscopic therapy is safe and efficient for treating lesions located in the rectum.
methodsThis is a retrospective observational study with an analysis of the medical records of all patients undergoing resection of rectal polyps.
resultsA total of 123 patients with rectal lesions were evaluated, with 59 men and 64 women of mean age 56 years. All patients underwent endoscopic resection: 70% with polypectomy and 30% with wide mucosectomy. Complete colonoscopy with removal of the entire rectal lesion occurred in 91%, while in 5% the preparation was inadequate and poor clinical conditions were an impeditive factor, and in 4% surgical treatment was indicated because there was an infiltrative lesion with central ulceration. Histological evaluation showed adenomas in 3.25%, hyperplasia in 7.32%, and hamartoma in 0.81%; low-grade dysplasia was identified in 34.96%, high-grade dysplasia in 51.22%, and adenocarcinoma in 1.63%, while one case (0.81%) was classified as erosion.
conclusionsPolyps in the rectum are common and were found in 37% of these colonoscopies. Adenomas with dysplasia were the most common form of Colorectal cancer . Therapeutic colonoscopy proved to be a safe and efficient method for the complete treatment of rectal lesions.
