Real-world effectiveness of omalizumab for severe allergic asthma treatment in Colombia.
Observational study in BMC pulmonary medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe allergic phenotype is responsible for more than 50% of severe asthma cases. In a stepwise approach, add-on treatments such as anti-IgE are used for severe allergic asthma (SAA). This study was aimed to describe the real-world effectiveness of omalizumab in adult and pediatric patients with SAA in Colombia.
methodsThis was an observational, non-interventional, retrospective study. Data from patients with SAA that received at least one month of treatment with omalizumab was obtained from medical records at eight sites in Colombia. Time-zero (t - 0) was defined as the date of initiation of omalizumab, and data was gathered for a 12-month period before t - 0 and a 12-month period after t - 0. Clinical outcomes, including exacerbations, were assessed at 6 and 12 months. Effectiveness of omalizumab was evaluated in terms of the reduction of the risk of exacerbations (annualized rate).
resultsWe included 143 patients with SAA. There was a decrease of 72.4% of the annualized rate of clinically significant asthma exacerbations during the year after omalizumab (from 1.74 before to 0.48 after) with a substantial reduction of the risk of exacerbations by 56.7% (RR [95% CI] 0.43 [0.30-0.63] p < 0,001).
conclusionThe use of omalizumab in Colombia as a treatment for SAA notably reduced the risk of clinically significant exacerbations. This study is the first to evaluate omalizumab real-life effectiveness in pediatric and adult patients in the country.
