Superficial temporal artery and branches in thai cadavers: anatomical variations, ethnic considerations, and filler injection safety.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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 superficial temporal artery (STA) and its branches have anatomical variation between populations. Detailed knowledge of these is essential for safe temporal flap harvest and filler injection. Data in Thai populations are limited. We examined STA morphology, dissecting 20 embalmed Thai hemifaces (14 male and 6 female), measuring diameters and distances of the STA and its branches, and developing a three-dimensional (3D) photogrammetry model. The STA bifurcated cephalic to the zygomatic arch in 90% of specimens. The mean diameter of the STA stem was 3.29 ± 1.08 mm, with frontal, parietal, and zygomatico-orbital (ZOA) branch diameters of 2.59 ± 0.78 mm, 2.51 ± 1.09 mm, and 1.24 ± 0.46 mm, respectively. The ZOA was present in 90% of specimens, with a jugale distance of 19.36 ± 9.45 mm. Sex comparison showed that the parietal branch was significantly larger in males (2.84 ± 1.08 mm) than in females (1.73 ± 0.67 mm, p = 0.013). Thai STA morphology appears broadly similar to other East Asian populations, supporting adaptation of regional filler injection protocols while underscoring the need for population-specific vascular mapping in clinical planning.
