Cutaneous nerve fields of the anteromedial lower limb-Determination with selective ultrasound-guided nerve blockade.
Article in Clinical anatomy (New York, N.Y.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07350252 (Postoperative Analgesia in Patients Undergoing Knee Replacement Surgery - a Study Comparing Intraoperative Local Infiltration Analgesia Only With Ultrasound-guided Nerve Blocks Added to Intraoperative Local Infiltration Analgesia, a Randomized Clinical Trial), which is not on this map.

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.

Abstract
backgroundThis study aimed to determine the peripheral cutaneous nerve fields (CNF), their variability, and potential overlap by selectively blocking the intermediate (IFCN) and medial (MFCN) femoral cutaneous nerves and the infrapatellar branch of the saphenous nerve (IPBSN) in healthy volunteers.
methodsIn this prospective study, ultrasound-guided nerve blockades of the IFCN, MFCN, and IPBSN in 14 healthy volunteers were administered. High-frequency probes (15-22 MHz) and 1 ml of 1% lidocaine per nerve were used. The area of sensory loss was determined using a pinprick, and all fields were drawn on volunteers' skin. A three-dimensional (3D) scan of all lower limbs was obtained and the three CNF and their potential overlap were measured.
resultsThe mean size of innervation areas showed a high variability of peripheral CNF, with 258.58 ± 148.26 mm
conclusionsOur study successfully determined CNF, their variability, and the overlap of the MFCN, IFCN, and IPBSN in healthy volunteers. Therefore, we encourage physicians to use selective nerve blockades to correctly determine peripheral CNF at the anteromedial lower limb.
