Cognitive-Motor Function and Anterior Cruciate Ligament Injury Risk: Exploring Relationships Between Clinical and Lab-Based Assessments.

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
Assessing cognitive-motor function following anterior cruciate ligament reconstruction may enable a more comprehensive assessment of readiness to return to sport. The primary purpose of this study was determining the relationship between measures of clinical cognitive-motor interference and laboratory-based second injury relevant biomechanics through a cross-sectional study.
methodsThirty-six individuals following anterior cruciate ligament reconstruction (26 females/10 males, 19.8 [1.8] y; 1.7 [0.1] m; 69.6 [12.8] kg, Tegner activity level 6.8 [1.8], 1.5 [0.6] y post anterior cruciate ligament reconstruction) participated in the study. We assessed 2 clinically feasible tests of cognitive-motor function: single (ST) and dual tasks (DT) for triple hop and medial-side hop. Laboratory-based tests involved motion capture assessment of jump landings from a 30-cm box followed immediately by a secondary jump. Conditions included, ST (anticipated secondary jump direction) and DT (unanticipated secondary jump direction). Primary outcome variables included DT change (DTC) of second anterior cruciate ligament injury predictors (limb asymmetry in knee extensor moment at initial contact, range of knee abduction angle for the involved limb, and uninvolved hip rotation net moment impulse). Correlations were used to identify associations between lab- (biomechanics) and clinic-derived (hop distance) outcomes. Secondary analyses with other risk-associated knee mechanics and patient-reported outcome measures were also performed.
resultsNo significant correlations were found between DTC clinical variables and DTC second anterior cruciate ligament predictors. However, significant relationships were observed between clinical and lab outcomes when considering ST or DT in isolation, such as ST range of knee abduction angle for the involved limb correlating with ST for triple hop for both limbs (Inv: r = -.436, Padj = .04; Uninv: r = -.453, Padj = .04).
conclusionsAssociations between cognitive-motor interference (ie, DTC) in clinical and lab tests were not found, but significant fair strength correlations appeared between clinical and lab variables when examining ST and DT performance, separately. Future prospective studies are needed to determine the predictive value of cognitive-motor function for injury rehabilitation decision making.
