Normative data of ultrasound quadriceps rectus femoris geometric values. The ECOSARC-2 Study.
Article in The journal of nutrition, health & aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectivesTo describe geometric muscle ultrasound normative values of Quadriceps Rectus Femoris (QRF) at mid-thigh in Spanish community-dwelling older adults. Secondary objectives included evaluating the associations between ultrasound measurements and physical function, muscle strength, frailty, and dependency in basic activities of daily living.
designCross-sectional study.
settingOutpatient clinics of Geriatric Departments at seven University Hospitals and three Primary care settings of Spain.
participants424 community-dwelling persons ≥70 years old. MEASUREMENTS: Ultrasound measurements were acquired using a Clarius® L7 HD3 probe. QRF thickness (QRFT), QRF area (QRFA), subcutaneous adipose thickness (SAT), total mid-thigh thickness (TTT), and pennation angle (PA) were calculated. Normative values are provided, and associations with comorbidity, dependency, strength, frailty and physical function are described.
resultsMean age was 81.5 years (range 70-99), 66.7% were female. Mean Barthel index was 93 (SD 11), and mean FRAIL score was 1.1 (1.2). Mean SPPB was 8.7 (SD 2.9) and mean grip strength was 20.7 (8.0). Median values of QRFT, QRFA, SAT, TTT, and PA for women and men were 14.2 / 16.1 mm, 5.4 / 6.4 cm
conclusionsThe ECOSARC-2 study provides normative values of geometric mid-thigh muscle ultrasound parameters in community-dwelling older adults. These values are essential for determining sex-specific cut-off points for conditions such as sarcopenia, frailty, malnutrition, and for predicting relevant outcomes.
