Identification of MicroRNAs in children with increased asthma bronchodilator usage in genetics of asthma in Costa Rica Study.

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
introductionUncontrolled or severe asthma results in symptomatic usage of short-acting ß2-agonist (SABA) usage. MicroRNAs (miRNAs) are posttranslational regulators that can influence asthma biology. This study aims to identify miRNAs that are associated with increased SABA usage.
methodsSmall RNA sequenced from blood serum of 1,132 children with asthma aged 6 to 14 years in the Genetics of Asthma in Costa Rica Study was used for this analysis. Logistic regression identified miRNAs in patients who required increased SABA usage. These miRNA were validated for association with SABA-induced bronchodilator responsiveness (BDR). Gene target pathway analysis was performed on validated miRNAs.
resultsTwenty-one miRNAs were significantly associated with increased SABA usage with OR ranging from 0.87 to 1.23. Two miRNAs, miR-378a-3p and miR-144-3p, had odds ratio 1.14 (1-1.29, p = .05) and 1.11 (1.01-1.22, p = .035), respectively, for increased SABA usage and were also significantly associated with bronchodilator response. Furthermore, a linear regression analysis involving these miRNA and bronchodilator response revealed that increased miR-378a-3p correlated with decreased BDR and increased expression of miR-144-3p correlated with improving pulmonary function with bronchodilators. In gene target Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, the erythroblastosis viral oncogene signaling pathway had among one of the highest fold enrichment and p-value.
conclusionIncreased expression of miR-378a-3p and miR-144-3p was seen in this patient population who required increased SABA usage. There were different bronchodilatory effects seen in these two miRNAs, suggesting different potential mechanisms underlying increased SABA usage.
