Assessment of Quadriceps Muscle Characteristics in Female Division I Athletes: A Validation Study of Wireless Probes Against Standard Ultrasound Units.

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
objectiveWireless ultrasound probes offer a quicker, more affordable option for muscle quality assessment compared with standard cart units, yet their effectiveness for evaluating larger muscles such as the rectus femoris in terms of cross-sectional area (CSA) and echo-intensity (EI) is unclear due to limited field of view. This study evaluates whether rectus femoris thickness and EI measured with a wireless probe correlate with CSA and EI obtained from a standard cart ultrasound.
methodsA cross-sectional, convenience sample of 29 division I college female athletes (age: 20.1 [1.1] y, height: 169.7 [7.4] cm, mass: 69.7 [10.0] kg) were recruited. Panoramic thigh ultrasound images were acquired with a standard ultrasound cart to assess the rectus femoris CSA and EI at 50% of the thigh length. A wireless ultrasound probe was used to acquire stationary images with the knee in the same position to assess rectus femoris thickness and EI. A Pearson product-moment correlation was used to determine the association between the muscle outcomes obtained with the standard cart ultrasound and wireless ultrasound probe.
resultsStandard ultrasound CSA (10.1 [2.0] cm2) and wireless ultrasound thickness (2.0 [0.3] cm) were strongly associated (r = .71, P < .001). Standard ultrasound EI (56.2 [5.1] arbitrary units) and wireless ultrasound EI (62.0 [6.3] arbitrary units) were moderately associated (r = .49, P = .007).
conclusionWireless ultrasound offers a fast and accessible method for assessing muscle thickness in female division I athletes when compared with similar muscle size and quality metrics measured on panoramic images acquired with a standard ultrasound cart. The echogenicity indices from wireless and standard ultrasound are significantly associated between units; however, wireless ultrasound systematically overestimates echogenicity compared with the standard.
