Minimal Detectable Change for the ImPACT Test Administered Remotely.
Article in Journal of athletic training, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
contextImmediate Postconcussion Assessment and Cognitive Testing (ImPACT) is one of the most widely used computerized neurocognitive assessment batteries in athletics and serves as both a baseline and postinjury assessment. It has become increasingly popular to administer the ImPACT baseline test in an unsupervised remote environment; however, whether the lack of supervision affects the test-retest reliability is unknown.
objectiveTo establish the minimal detectable change (MDC) of composite scores from the ImPACT test when administered to National Collegiate Athletic Association Division I student-athletes in an unsupervised remote environment before 2 consecutive athletic seasons.
designCross-sectional study.
settingParticipants were provided with a unique link and detailed written instructions on how to complete the ImPACT test at home. PATIENTS OR OTHER
participantsDivision I student-athletes. MAIN OUTCOME MEASURE(S): Remote baseline ImPACT results from the 2020-2021 and 2021-2022 athletic seasons were analyzed. The MDC was calculated at the 95%, 90%, and 80% CIs for each of the ImPACT composite scores as well as the average and SD.
resultsThe MDC at the 95% CI was 18.6 for the verbal memory composite score, 24.44 for visual memory, 8.76 for visual motor, 0.14 for reaction time, and 6.13 for impulse control. One-way repeated-measures multivariate analysis of variance, repeated-measures analysis of variance, and Wilcoxon signed ranks tests suggested no difference in the composite scores and impulse control between time points.
conclusionsThe ImPACT composite scores and impulse control did not change between the 2 remote testing time points when administered approximately 1 year apart. Our study suggests that the MDC serves as a clinician's guide for evaluating changes in ImPACT baseline scores and in making clinical judgments on sport-related concussion when the test is administered at home.
