1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study aimed to obtain morphometric data of the pituitary gland and sella turcica in Hamdani sheep using computed tomography (CT) and to assess sexual dimorphism.

methodsCT scans of skulls from 16 healthy adult Hamdani sheep (8 males, 8 females) were analysed using RadiAnt DICOM Viewer (64-bit). Morphometric measurements of the pituitary gland were obtained from transverse (length, height, width), dorsal (length, width), and sagittal (length, height) sections, and these values were used to calculate the volume of the gland. Additionally, using the pituitary gland measurements, the transverse index (TI), sagittal index (SI), and dorsal index (DI) were calculated. Furthermore, nine osteometric parameters including surface area and 12 ratio values were obtained from sagittal images of the sella turcica.

resultsStatistical analysis showed that both the linear dimensions and volume of the pituitary gland and sella turcica were greater in males. The pituitary gland volume was 1.211 ± 0.166 cm

conclusionsCT imaging revealed marked morphometric differences between sexes in Hamdani sheep, confirming sexual dimorphism. These findings may contribute to future research in areas such as anatomical reference, sex determination, clinical diagnosis, pituitary and sella turcica pathology, veterinary surgery, and zooarchaeology.
