Test-Retest Reliability, Learning Effect and Measurement Error of the Modified Shuttle Test (MST) in Children With Asthma: A Multicenter 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
objectiveTo investigate test-retest reliability, measurement error (standard error of measurement [SEM] and minimum detectable difference [MDD]), and the learning effect of the Modified Shuttle Test (MST) in children with asthma.
methodsMulticenter cross-sectional study including clinically stable children aged 6-12 years with asthma. Lung function and exercise capacity were assessed using MST. Intraclass Correlation Coefficient (ICC) was calculated to assess test-retest reliability. The first and second tests were compared using the paired Student's t-test to assess differences between tests. SEM and MDD were calculated to quantify measurement error.
resultsOne hundred and twenty three children were included (71 boys [57%]; median age 9 [7-10] years). The mean distance covered in the best MST was 611 ± 214 meters (confidence interval [95% CI] = 573-649meters). The MST showed an excellent test-retest reliability (ICC = 0.96; 95% CI: 0.95-0.97). Distance was significantly lower in the second test than in the first (574 ± 218 vs. 601 ± 216 m; p = 0.0001). Learning effect was -27 ± 79 (4% ± 14%), the SEM was 56 meters (9.5%), and the MDD was 156 m (26.6%).
conclusionThe MST demonstrated excellent test-retest reliability and acceptable measurement error for assessing exercise capacity in children with asthma. Although a systematic difference was observed between tests, there was no evidence of a consistent learning effect, with individual variability in repeated performance.
