Hip abduction with hip extension produces the largest obturator nerve displacement: a cadaveric investigation.

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 obturator nerve may be injured during surgery or trauma. Neurodynamic testing (NDT) is theorized to assist in obturator nerve injury identification, but the optimum hip position for NDT has not been biomechanically supported.
objectivesThis study evaluated the displacement and strain of the obturator nerve within the pelvis using three NDT positions of the hip (neutral, flexion, and extension) combined with hip abduction.
designOne-way repeated measures.
methodsNine cadavers were selected by consecutive sampling, and metal markers were glued to the exposed intrapelvic obturator nerves
resultsThe obturator nerve displaced distally from the starting position during end-range hip abduction with the sagittal hip position in neutral (mean = 2.76 ± 2.46 mm;
conclusionObturator nerve NDT using end-range hip abduction with the sagittal hip position in neutral or extension significantly displaces the nerve distally, suggesting these positions may be most useful when performing NDT of the obturator nerve.
