[A clinical follow-up study of children with well-controlled asthma after withdrawal of low-dose inhaled corticosteroids].

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
objectiveTo study the incidence of acute attacks of asthma and dynamic changes in laboratory markers in children with well-controlled asthma after the withdrawal of low-dose inhaled corticosteroids (ICS), and to provide a basis for optimal long-term control regimens for children with asthma.
methodsA total of 63 children with well-controlled asthma were enrolled as subjects. According to their parents' wishes, they were continuously administered with ICS (ICS treatment group; n=35) and without ICS (ICS withdrawal group; n=28). They were followed up for 18 months. The incidence of acute attacks of asthma was evaluated, dynamic monitoring was performed for pulmonary function and fractional exhaled nitric oxide (FeNO), and childhood asthma control test (C-ACT) was performed every three months.
resultsAt 3, 6, 9, and 12 months of follow-up, there was no significant difference in FeNO between the ICS treatment and withdrawal groups (P>0.05). However, at 15 and 18 months of follow-up, the withdrawal group had a significantly higher level of FeNO than the ICS treatment group (P<0.05). There was no significant difference in the C-ACT score between the two groups at all time points of follow-up (P>0.05). At 3, 6, 9, and 12 months of follow-up, there were no significant differences between the two groups in the percentage of forced expiratory volume in 1 second, the ratio of forced expiratory volume in 1 second to forced vital capacity, percentage of predicted maximum mid-expiratory flow (MMEF%), and maximal expiratory flow at 50% of vital capacity (MEF50) (P>0.05), while at 15 and 18 months of follow-up, the ICS treatment group had significantly higher MMEF% and MEF50 than the withdrawal group (P<0.05). During follow-up, 3 children (9%) in the ICS treatment group and 8 (29%) in the withdrawal group experienced acute attacks of asthma (P=0.0495).
conclusionsContinuous inhalation of low-dose ICS can maintain the stability of pulmonary function and reduce acute attacks of asthma in children with well-controlled asthma.
