Saudi Arabian real-life experience with biologic therapy in severe asthma.
Article in Multidisciplinary respiratory medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
backgroundSevere asthma (SA) is a common health problem associated with increased morbidity and mortality and high medical costs. Biological therapies have emerged in recent decades as promising treatment options for patients with high type 2 (T2) SA. This retrospective observational study from Saudi Arabia aimed to investigate the effects of additional biologics therapy on reducing oral corticosteroid (OCS) consumption, frequency of asthma exacerbations, improvement in lung function, and asthma control.
methodsThis multicenter observational study enrolled a cohort of 97 patients from March 2019 to February 2021. Outcomes of anti-IgE, anti-IL5/IL5R, and anti-IL4R therapies in severe type 2 asthma were recorded and analyzed in terms of number of exacerbations (emergency visits or hospitalizations required), asthma symptoms, and use of oral corticosteroids, blood eosinophil count, asthma control according to GINA classification, and FEV
resultsNinety-seven patients were included in the analysis The mean age was 46.7±14.1 years, and 69.1% of them were female. The average duration of biological treatment was 16.4±6.8 months. At the time of data collection, the four biologic therapies reduced the exacerbation rate per year from 82/97 (84.5%) to 14/97 (14.4%) with a percent improvement of 83% from 2.9 per year in the year before biologic treatment to 1.6 per year (p<0.001). OCS was reduced from 75/97 (77.3%) to 10/97 (10.3%) for a percent improvement of 86.7%, and the average OCS dose decreased from 7.12 mg to 6.8 mg. Mean blood eosinophil count also decreased after biologic therapy from 750.5±498.5 to 188.0±122.4 cells/μl, most significant result achieved with benralizumab, and mean FEV
conclusionsBiologic as add-on therapy for high T2 SA was found to reduce asthma exacerbations, systemic glucocorticoid doses, and SA symptoms.
