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 &

aimsThis study compares the effectiveness and safety of infliximab and adalimumab in biologic-naive patients with ulcerative colitis (UC), in a nationwide register-based propensity score-matched cohort study.

methodsFrom 1719 adults with UC, between ages 15 and 75 years in Denmark treated with either infliximab or adalimumab as their first biologic agent, we compared rates of all-cause hospitalization, UC-related hospitalization, major abdominal surgery, and serious infections after a variable 2:1 propensity score matching, accounting for baseline clinical characteristics, disease severity, health care utilization, and use of UC-related medications.

resultsAs compared with infliximab-treated patients, adalimumab-treated patients had higher rate of all-cause hospitalization (hazard ratio [HR], 1.84; 95% CI, 1.18-2.85) and a trend toward higher rate of UC-related hospitalization (HR, 1.71; 95% CI, 0.95-3.07), particularly in a stratum of patients on concomitant immunomodulator therapy. However, risk of abdominal surgery (HR, 1.35; 95% CI, 0.62-2.94) was not different between the 2 treatment groups. Risk of serious infection requiring hospitalization was significantly higher in adalimumab-treated patients (HR, 5.11; 95% CI, 1.20-21.80).

conclusionsIn this nationwide propensity score matched-cohort study of biologic-naive adults with UC, use of adalimumab as first-line biologic over infliximab was associated with higher risk of hospitalization and serious infections, although risk of surgery was not different. In the absence of head-to-head trials, this evidence may assist patients, health care providers, purchasers, and policy makers to make informed decisions that may improve health care in UC.
