Stepping down therapy for well-controlled mild asthma: an experience from University Medical Center at Ho Chi Minh City.
Article in Asia Pacific allergy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundStepping down treatment for well-controlled mild asthma is challenging to clinicians. The step-down strategy using regularly-intermittent low-dose inhaled corticosteroid has been applied at the University Medical Center (UMC) of Ho Chi Minh City, called as "UMC" approach.
objectiveThis study aimed to evaluate the efficiency of UMC step-down strategy in well- controlled mild asthma.
methodsA real-world retrospective descriptive study was conducted at UMC from 2009 to 2018. All asthmatic patients (age ≥ 12) who received step-down therapy using this UMC approach were evaluated.
resultsAmong 2,072 asthma patients to be treated with UMC step-down strategy, only 112 subjects were eligible. The median age was 38.5 years and female was 62.5%. Most patients at their initial presentation were indicated step 4 treatment (87.5%). The controller medications before initiation of UMC treatment included fluticasone propionate 125 μg once-daily, salmeterol/fluticasone propionate 25/125 μg once-daily, and formoterol/budesonide 4.5/160 μg once-daily. After being treated with the UMC approach, the rates of well-controlled asthma ranged from 67.6% to 91.1%. During 1 year with UMC treatment, pulmonary function remained stable and only 7 subjects (6.3%) developed exacerbation.
conclusionThe UMC step-down treatment for well-controlled mild asthma was relatively efficient in maintaining asthma control, stabilization of pulmonary function, and reducing risk of severe exacerbation.
