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
The accurate identification of peripheral nerves using ultrasound is essential for the safe and effective application of image-guided interventions in pain management. The femoral nerve (FN) and saphenous nerve (SN) are common targets for peripheral nerve invasive techniques, yet their depth and anatomical variability can impact procedural success. The objective was to describe the ultrasound anatomy of the FN and SN in healthy individuals and analyze how anthropometric variables predict its location.
designA cross-sectional study was conducted in 30 healthy participants. Ultrasound measurements included subcutaneous tissue thickness, nerve depth, and cross-sectional area of the FN and SN. Anthropometric data such as BMI, limb length, and circumference measurements were also recorded. Pearson correlations and hierarchical regression models were used to identify predictors of nerve location.
resultsNo significant side-to-side differences were found for any variable (p > 0.05). Subcutaneous tissue thickness and limb circumference showed strong correlations with nerve depth. The final hierarchical regression model explained 67.0% of the variance in skin-to-FN distance and 82.3% for skin-to-SN distance. Subcutaneous tissue at the inguinal region and mid-thigh, as well as lower limb length and mid-thigh circumference, were significant predictors for FN depth. For the SN, subcutaneous thickness at mid-thigh, mid-thigh circumference, and inguinal subcutaneous tissue were the most relevant predictors.
conclusionAnthropometric variables, especially subcutaneous tissue thickness and limb circumferences, are reliable predictors of FN and SN depth in healthy subjects. These findings support the use of simple anatomical measures to improve planning and safety in ultrasound-guided procedures.
