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.

2 · The registry

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

aimsThe health consequences of coronavirus disease 2019 [COVID-19] among patients with ulcerative colitis [UC] and Crohn's disease [CD] remain largely unknown. We aimed to investigate the outcomes and long-term effects of COVID-19 in patients with UC or CD.

methodsWe conducted a prospective, population-based study covering all Danish patients with CD or UC and confirmed COVID-19 between January 28, 2020 and April 1, 2021, through medical records and questionnaires.

resultsAll 319 patients with UC and 197 patients with CD who developed COVID-19 in Denmark were included in this study and compared with the Danish background population with COVID-19 [N = 230 087]. A significantly higher risk of COVID-19-related hospitalization was observed among patients with UC (N = 46 [14.4%], relative risk [RR] = 2.49 [95% confidence interval, CI, 1.91-3.26]) and CD (N = 24 [12.2%], RR = 2.11 [95% CI 1.45-3.07]) as compared with the background population (N = 13 306 [5.8%]). A similar pattern was observed for admission to intensive care (UC: N = 8 [2.51%], RR = 27.88 [95% CI 13.88-56.00]; CD: N = 3 [1.52%], RR = 16.92 [95% CI 5.46-52.46]). After a median of 5.1 months (interquartile range [IQR] 4.5-7.9), 58 [42.3%] and 39 [45.9%] patients with UC and CD, respectively, reported persisting symptoms which were independently associated with discontinuation of immunosuppressive therapies during COVID-19 (odds ratio [OR] = 1.50 [95% CI 1.07-10.22], p = 0.01) and severe COVID-19 (OR = 2.76 [95% CI 1.05-3.90], p = 0.04), but not with age or presence of comorbidities.

conclusionIn this population-based study of 516 patients with IBD and COVID-19, 13.6% needed hospitalization and 2.1% required intensive care. Furthermore, sequelae were frequent, affecting 43.7% of COVID-19-infected patients. These findings might have implications for planning the healthcare of patients in the post-COVID-19 era.
