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

backgroundDupilumab was equally effective among all racial subgroups in clinical trials, but a direct comparison in daily practice is lacking.

objectivesTo investigate the effectiveness of dupilumab in patients with atopic dermatitis (AD) in the Netherlands and Japan over 80 weeks of treatment.

methodsA longitudinal comparative cohort study was conducted in patients with AD who were treated with dupilumab in daily practice. We used linear mixed-effects models to determine changes over time.

resultsWe found statistically significant differences in sex, disease onset, body mass index and therapeutic history between Dutch (n = 208) and Japanese (n = 153) patients. The baseline Eczema Area and Severity Index (EASI) score was higher in Japanese patients (23·8 vs. 14·8), while baseline Patient-Reported Outcome Measures (PROMs) were higher in Dutch patients. EASI scores decreased quickly to a level indicating 'mild disease' (EASI < 7), and remained low in both countries. However, PROMs showed different trajectories with better scores in Japan.

conclusionsDupilumab showed significant, comparable and sustained improvement of EASI scores in Japanese and Dutch patients. However, we found striking differences in the effect on PROMs between the countries, with a better outcome in Japanese patients.
