The effect of asthma specialist intervention on asthma control among adults.
Article in The World Allergy Organization journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background: Various ways to improve asthma control have been studied, with only a modest effect. Purpose: To evaluate the effect of asthma specialist visit on asthma control among adult asthma patients. Patients and methods: This matched cohort study included patients ages 21-50 with asthma and at least 1 visit to an asthma specialist. Patients were compared to adult asthma patients treated only by primary care physicians. The study outcomes, included use of asthma medication, healthcare visits, and mortality. All outcomes were compared one year before and after specialist visit. Results: 4166 pairs were included in the study. In the study group, a statistically significant decrease in the average number of relievers (1.5 ± 3.2 vs. 1.17 ± 2.9, p < 0.001) and systemic steroids purchased (0.53 ± 1.2 vs. 0.4 ± 1.2, p < 0.001), with an increase in average number of inhaled steroid purchased (1.6 ± 2.5 vs. 2.3 ± 33, p < 0.001) was seen over time. A significant decrease in the average number of PCP visits (9.5 ± 7.2 vs. 8.9 ± 7.3, p < 0.001), emergency department (ED) visits (0.46 ± 1 vs. 0.4 ± 0.9, p = 0.05) and all-cause hospitalization (0.03 ± 0.22 vs. 0.01 ± 1.9, p < 0.001) was seen in the study group but not in controls. Generalized linear modeling demonstrated an overall significant effect of specialist intervention for all parameters (p < 0.01), except ED visits (p = 0.06). During follow-up, eight (0.2%) study group patients vs. 19 (0.5%) controls died (p = 0.03). Conclusion: We found that asthma specialist intervention significantly improved asthma outcomes in adults. Referring adult asthma patients to an asthma specialist should be a goal of asthma management plans. Trial registration: Not relevant.
