Health care resource utilization of patients with asthma and food allergy initiating omalizumab.

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: Patients with comorbid asthma and food allergy (FA) are at increased risk of adverse outcomes for both conditions. Omalizumab, a biologic for moderate to severe persistent asthma, received recent approval for FA. Objective: We sought to compare FA-, asthma/FA-related, and all-cause health care resource utilization and costs before and after omalizumab initiation among patients with asthma and FA. Methods: This study retrospectively analyzed data from IQVIA PharMetrics Plus claims among patients who were 6 years or older, had asthma and FA (medical claim for FA or anaphylactic reaction due to food), had initiated omalizumab between 2018 and 2021, and had 12 months of data before (baseline) and after (follow-up) omalizumab initiation (index date). Results: Of 523 patients who initiated omalizumab (mean age, 33.1 years; 71.5% female), the prevalence of FA-related (12.4% vs 4.8%), asthma/FA-related (25.0% vs 15.5%), and all-cause (44.6% vs 30.2%; all Conclusions: FA-related, asthma/FA-related, and all-cause emergency department visits and hospitalizations significantly reduced in the 12 months after omalizumab initiation. These results provide valuable and timely real-world evidence that omalizumab has the potential to reduce the acute care utilization in patients with comorbid asthma and FA.
