Validation of an Asthma Knowledge Tool to Assess the Efficacy of Comprehensive Asthma Education.

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
introductionAsthma is a leading cause of chronic disease in children, and poor control is often associated with a lack of asthma knowledge, which can be improved through education. Thus, it is important to have a validated tool that measures asthma knowledge. We aimed to develop an asthma knowledge tool to assess the efficacy of comprehensive asthma education for caregivers of children with asthma.
methodsAn asthma knowledge tool was designed using existing questionnaires and pilot tested amongst 10 asthma experts and 20 parents who had previously received asthma education. The Children's Hospital of Eastern Ontario Asthma Knowledge Tool (CHAT) consists of 35 true/false questions. The CHAT was then prospectively administered to caregivers between June 2021 and 2023 before receiving education, < 7 days following education, and < 2 weeks after completing posttest 1. Internal responsiveness of the CHAT was measured by comparing pre- and posttest scores using paired t-tests and determining effect size. Test-retest reliability was calculated using the two-way mixed effect Intraclass correlation coefficient (ICC) for posttest scores.
resultsMean CHAT scores amongst 129 participants increased by 6.2 points between pretest to posttest 1 (95% CI 5.4-7.0), with an estimated effect size of 1.2, indicating a large change (p < 0.001). Test-retest reliability was "good" to "excellent" with an estimated ICC of 0.85 between posttests.
conclusionThe CHAT exhibited good discrimination, and reliably measured a significant improvement in knowledge scores following asthma education. The CHAT is a validated asthma knowledge tool for caregivers of children with asthma, having implications for future quality improvement and research studies.
