Interpreting Change in Sport Concussion Assessment Tool-5th Edition (SCAT5) Scores in National Rugby League Women's Premiership Players.

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
backgroundThe Sport Concussion Assessment Tool (SCAT) is a multimodal, evidence-based tool designed for repeat administration at baseline, pre-season and/ or for post-injury assessments, following a sport related concussion. Repeat administration of concussion assessment tools requires clinicians to understand the instrument's stability and test-retest reliability. Typically, clinicians compare post-injury scores with baseline test results in order to determine whether a clinically significant change has occurred. The National Rugby League Women's (NRLW) Premiership was created in 2018, with a concussion management process requiring annual pre-season baseline medical assessments of players using the Sport Concussion Assessment Concussion Tool-5th Edition (SCAT5). Although baseline normative data have been published for the SCAT5, reliability data are limited in women. The purpose of this study was to examine the one-year test-retest reliability of the SCAT5 component scores, and to develop reliable change indices, for the women's league.
resultsParticipants were 63 NRLW players (mean age = 26.9 years, SD = 5.5) from the 2018-2019 and 2019-2020 seasons. Team medical staff conducted the baseline SCAT5 assessments each year. Test-retest reliability estimates for each of the SCAT5 components were low to moderate (ICCs = 0.28-0.57). The following change scores, reflecting worsening, occurred in 20% or fewer of the sample: +3 symptom number, + 4 symptom severity, and - 2 on the Standardized Assessment of Concussion total score. A change of + 2 total modified Balance Error Scoring System errors occurred in fewer than 10% of the NRLW players between the test and retest.
conclusionSCAT5 scores had low to moderate test-retest reliability across a one-year period. Reliable change scores for the SCAT5 were developed in this study for use with professional women rugby league players. When evaluating post-injury SCAT5 scores, it can be helpful to consider both what the score means compared to normative reference values and compared to the athlete's individual baseline scores.
