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

backgroundWe aimed to investigate the effectiveness of omalizumab, a monoclonal anti-immunoglobulin E antibody, in Chinese patients with moderate-to-severe allergic asthma in real-world clinical practice.

methodsThis single-centre, prospective, observational study included Chinese patients aged 14-75 years with moderate-to-severe allergic asthma according to the Global Initiative for Asthma criteria. Omalizumab was administered subcutaneously, and the investigator collected real-world data on exacerbations, steroid exposure, pulmonary function and laboratory assessments at weeks 16, 24, 52, 104 and 156 after treatment initiation. The primary outcome was reduced exacerbations, measured as the proportion of patients with exacerbations in the year following omalizumab initiation. Bowker's test for paired proportions was performed to compare exacerbation rates before and after treatment initiation. A generalised linear mixed model was used to compare the number of exacerbations.

resultsThe mean treatment duration was 46.6 weeks for the full analysis set (n=398). The proportion of patients with exacerbations in the year before and after omalizumab initiation was 80.4% (181/225) and 18.7% (42/225) (difference: -61.8%, 95% CI -68.5 to -54.0, p<0.0001), respectively. At week 52, 67.4% of patients discontinued oral corticosteroids, and 19.5% reduced inhaled corticosteroids. The Asthma Control Test scores increased by 4.6 at week 52 from baseline (p<0.001). Forced expiratory volume in 1 s increased by 11.2% and 9.0% at weeks 24 and 52, respectively, from baseline (p<0.01). Injection site reactions (5.2%) were the most frequently reported adverse event.

conclusionsIn real-world clinical practice, omalizumab treatment remarkably reduced exacerbations in Chinese patients with moderate-to-severe asthma. Omalizumab reduced the use of oral corticosteroids and improved asthma control and pulmonary function.
