Long-Term Course and Prognostic Factors in Pediatric Ulcerative Proctitis: A Multicenter Cohort Study.

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
backgroundAlthough ulcerative proctitis (UP) in children is considered relatively mild, some patients have proximal disease extension and require immunosuppressive treatment. We investigated clinical characteristics and course of refractory UP in a multicenter pediatric cohort.
methodsAnalyzing data obtained between 2013 and 2022 at 10 institutions specializing in pediatric inflammatory bowel disease, we elucidated natural history and factors predicting a need for immunosuppressive UP treatment. We compared patients given immunosuppressants and/or biologic agents (immunosuppressive treatment group) with those given 5-aminosalicylic acid (5-ASA) alone (5-ASA group).
resultsFifty-five patients were followed for 3.5 years. The median Pediatric Ulcerative Colitis Activity Index at diagnosis was 20. The commonest treatment, 5-ASA suppository monotherapy in 40% of patients, showed the worst compliance. Clinical remission was achieved at least once in 95% of all patients. Disease extension beyond the splenic flexure occurred in 51%. Immunosuppressive treatment was given to 37%; biologic agents were used for 18%. Rates of endoscopically demonstrated inflammation, including Ra/Rs at diagnosis and extension beyond the left-sided colon, were higher in the immunosuppressive treatment group (70% vs 38%, P < 0.05; 95% vs 27%, P < 0.0001). The log-rank test and multivariate Cox proportional hazards regression showed that time to first clinical remission exceeding 3 months predicted the need for biologics.
conclusionThe typical initial treatment of pediatric UP was 5-ASA suppositories, despite poor compliance. Biologics or other immunosuppressive treatments were needed in 37% of patients. Close follow-up with adjustment of treatment should be considered in children with UP as its clinical course varies.
