A biceps-bicaudatus sartorius muscle: dissection of a variant with possible clinical implications.
Article in Anatomy & cell biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The current cadaveric report describes an unusual morphology of the sartorius muscle (SM), the biceps-bicaudatus variant. The SM had two (lateral and medial) heads, with distinct tendinous origins from the anterior superior iliac spine. The lateral head was further split into a lateral and a medial bundle. The anterior cutaneous branch of the femoral nerve emerged between the origins of the lateral and medial heads. SM morphological variants are exceedingly uncommon, with only a few documented cases in the literature, and several terms used for their description. Although their rare occurrence, they may play an important role in the differential diagnosis of entrapment syndromes, in cases of neural compressions, such as meralgia paresthetica, while careful dissection during the superficial inter-nervous plane of the direct anterior hip approach is of utmost importance, to avoid adverse effects due to the altered SM morphology.
