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

backgroundComparisons of second-line anti-tumour necrosis factor (TNF) agents and vedolizumab are sparse.

aimTo evaluate the effectiveness of anti-TNF agents compared to vedolizumab as second-line biologics in inflammatory bowel disease (IBD).

methodsA propensity score-matched cohort was created using Swedish nationwide registers. Patients with Crohn's disease or ulcerative colitis, exposed to first-line anti-TNF treatment, who initiated a second anti-TNF agent or vedolizumab in 2014-2016 (N = 1363) were included. The primary outcome was drug survival at 12 months. Secondarily, we assessed survival without IBD-related hospitalisation, IBD-related surgery, antibiotics, or hospitalisation because of infection, and also corticosteroid exposure.

resultsAfter 1:1 propensity score matching, 400 patients (Crohn's disease, N = 198; ulcerative colitis, N = 202) remained. For Crohn's disease, drug survival was 73% in the vedolizumab group vs 74% in the anti-TNF group (difference: 1 percentage point; 95% confidence interval [CI]:-11-13; P = 0.87). Survival without IBD-related hospitalisation (82% vs 88%), surgery (82% vs 89%), antibiotics (65% vs 71%), hospitalisation due to infection (95% vs 88%) and corticosteroids (58% vs 48%) were not statistically significantly different between groups. For ulcerative colitis, drug survival was 69% in the vedolizumab group vs 62% in the anti-TNF group (difference: -7 percentage points; 95% CI: -20 to 6; P = 0.30). Vedolizumab-treated patients had lower survival without IBD-related hospitalisation (82% vs 93%, P = 0.02). Survival without colectomy (93% vs 97%), antibiotics (81% vs 70%), hospitalisation due to infection (92% vs 92%) and corticosteroids (58% vs 48%) were not statistically significantly different.

conclusionsBased on Swedish clinical practice, the effectiveness and safety of second-line anti-TNF and vedolizumab at 12 months appeared largely similar.
