Depth and hemodynamics of the angular artery in the pyriform space: A cross-sectional study with Doppler ultrasonography.

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
Purpose: Knowledge of the angular artery (AA) anatomy in the nasolabial fold is essential to prevent necrosis during esthetic procedures. This study aimed to assess the depth and hemodynamics of the AA in the pyriform space using 2-dimensional ultrasonography (USG), as well as color and spectral Doppler imaging. Materials and Methods: This study evaluated AA diameter, epidermis-AA distance (EP-AA), AA-bone distance (AA-BO), systolic velocity, diastolic velocity, pulsatility index, and resistance index. These parameters were analyzed in relation to independent variables, including age, sex, and body mass index (BMI). The study sample consisted of 58 Brazilian participants, with both hemifaces independently assessed by 2 trained examiners. Statistical analyses of the variables were performed with a significance level of 5%. Results: The EP-AA distance was greater in men (5.8 mm) than in women (4.8 mm, Conclusion: USG demonstrated that AA depth in relation to the epidermis is greater in men and in individuals with higher BMI. Aging is associated with a reduction in both the diameter of the AA and its diastolic and systolic velocities.
