Article in Hepatology international, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07341282 (Investigation of Vancomycin Efficacy in Patients With Ulcerative Colitis and Primary Sclerosing Cholangitis), which is not on this map. Cited by 25 papers.

1 · What the graph read from it

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.

Abstract

BACKGROUND AND

aimsPrimary sclerosing cholangitis (PSC) is associated with an increased risk of hepatobiliary and colorectal cancer, but the risks of other cancer forms have not been explored. The aim of this study was to evaluate the risk of intestinal and extraintestinal cancers in a large, well-defined cohort of PSC patients. MATERIAL AND

methodA matched cohort study of Swedish PSC patients was performed with up to ten comparators for each patient, matched for sex, age, and residency. The data were retrieved from national registers. Patients were followed from PSC diagnosis until cancer diagnosis, liver transplantation, first emigration date, death, or December 31, 2016. The risk of cancer was estimated using the Kaplan-Meier method and Cox regression models.

resultsIn total, 1432 PSC patients with a verified diagnosis and 14,437 comparators were studied. The mean follow-up time was 15.9 years. Eighty-eight percent of the PSC patients had concomitant inflammatory bowel disease. PSC patients ran significantly increased risks of developing any cancer [HR 3.8, 95% confidence interval (CI) 3.3-4.3], hepatobiliary cancer (HR 120.9, 95% CI 72.0-203.1), colorectal cancer (HR 7.5, 95% CI 5.6-10.0), pancreatic cancer (HR 8.0, 95% CI 3.2-20.2), gastric cancer (HR 4.2, 95% CI 1.5-11.3), small bowel cancer (HR 21.1, 95% CI 3.5-128.2), and lymphoma (HR 3.0, 95% CI 1.6-5.7). PSC was not associated with a lower risk of any cancer form.

conclusionsPSC patients have a four times overall increased risk of developing cancer compared to the general population, with increased risk of developing hepatobiliary, colorectal, and pancreatic cancer, as well as lymphoma.
