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
purposeTo provide a detailed examination of the arterial blood supply to the middle third of the nasal skin through cadaveric dissections, identifying the primary arterial sources and their precise locations.
methodsCadaveric dissections were performed on 14 hemifaces from fresh specimens. The main feeding arteries and their branches were carefully dissected under magnification. Morphometric characteristics of the specimens, along with the caliber of the arteries and their branches vascularizing the mid-third nasal skin were recorded, and statistically analyzed.
resultsFour main arteries were identified as responsible for the blood supply to the mid-third of the nasal skin: the facial artery, the nasal branch of the infra-orbital artery (nbIOA), the dorsal nasal artery, and the upper branches of the columellar plexus. The lateral nasal artery (LNA) and the nbIOA were the main contributors, each providing significantly larger arterial branches than the other sources (1.8 ± 0.8 branches of 0.67 ± 0.2 mm for the LNA, p-value < 0.001-1 ± 0 branches of 0.55 ± 0.17 mm for the nbIOA, p-value < 0.01). The largest arterial branch consistently penetrated the lateral and inferior angle of the mid-third nasal skin, originated either from the LNA or nbIOA.
conclusionThe LNA and nbIOA endorse crucial roles in the arterial blood supply to the mid-third nasal skin. Despite the variability in vascular anatomy, a consistent pattern of arterial supply with convergence in the depth of the alarfacial groove was observed. Understanding these patterns is vital for improving surgical precision and reducing the risk of complications in both aesthetic and reconstructive surgeries.
