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
purposeThe surgical approach for midfoot injuries classically requires dual dorsal incision and identification of the neurovascular structures that are susceptible to injury during the surgery. The aim of this study was to map the topographic anatomy of the dorsum of the foot along with tarsal joints for the dorsal approach of midfoot surgery that would facilitate the surgery and minimize the risk of neurovascular injuries for surgeons who specially focus on foot and ankle injuries.
methodsThe dorsum of the foot was evaluated in 12 feet injected with latex containing a red colorant to visualize the arterial vessels. The navicular line, originating from the navicular tuberosity (NT) and passing over the dorsum of the foot, was used as a reference line. Dorsal foot neurovascular structures including cutaneous branches and muscles were mapped with respect to the tarsal joints and navicular line.
resultsThe deep peroneal nerve and dorsalis pedis artery were coursing between the base of the first and second metatarsal bones over which the tendon of the extensor hallucis brevis muscle was passing. The tendon of extensor hallucis brevis was crossing over the deep peroneal nerve and dorsalis pedis artery 55.2 mm superior and 45.0 mm lateral, respectively, from the NT.
conclusionThis cadaver study supplies a detailed topographic map of the dorsum of the foot using the tarsal joints and NT as landmarks for protecting the neurovascular structures to facilitate midfoot surgeries for sports medicine surgeons who specially focus on foot and ankle injuries.
