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
purposeDespite the increasing use of craniofacial morphometry worldwide, there is a lack of population-specific normative data based on high-resolution 3D skull models for the Turkish population. This study aimed to fill this gap by investigating cephalic, nasal, and orbital indices using precise measurements derived from 3D models, and to evaluate their variations according to sex, age, and laterality.
methodsIn this retrospective study, multidetector computed tomography (MDCT) data of 240 adults (120 males, 120 females) without any deformity or trauma were used. Cephalic, nasal and orbital indices were calculated using precise anatomical landmarks on high-precision 3D skull models obtained from these data, and comprehensive statistical analyses were performed with SPSS 20.0.
resultsCranial length, piriform aperture width and orbital width were higher in males than females (p < 0.001). Orbital height was higher in females than in males (p = 0.003). Cephalic and orbital indices were higher in females, whereas nasal index was higher in males (p < 0.001). In terms of anatomical asymmetry, left orbital measurements were higher than the right side in both sexes (p < 0.001). In addition, as age increased, the skull shape shifted towards dolichocephalic type, orbital proportions decreased and nasal aperture widened (p < 0.001).
conclusionThe findings clearly revealed sex-related differences, age-related morphological changes, and significant orbital asymmetry. The obtained data may increase the accuracy of sex estimation in forensic anthropology, support preoperative planning in craniofacial and reconstructive surgeries with region-specific reference measurements, and form the basis for anthropological research by contributing to ethnic and regional morphometric databases.
