Morphological and topographic analysis of the sesamoid bones of the hand: A radiographic institution-based descriptive cross-sectional study.

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 goal of this study was to establish the incidence, topographic location and measurements of sesamoid bones of the hand. This cross-sectional study involved 102 antero-posterior plain radiographs of the hand. Among them, 56 were female patients, and 46 were male patients. The films were scrutinized for their topography and number of sesamoid bones. Radiant Dicom viewer software (Poland, version 4.2.1.17555, 64-bit) was used to determine morphometric parameters such as the length and breadth of the sesamoid bones. Side, age and sex comparisons of the parameters were performed via the chi-square test. The sesamoid bone was observed at the first metacarpophalangeal joint, medially and laterally, in 99% and 80.6% of the patients, respectively. The length and breadth of the medial sesamoid and lateral sesamoid were 0.49 ± 0.07 cm and 0.40 ± 0.07 cm, 0.52 ± 0.10 cm and 0.37 ± 0.08 cm, respectively. The second, third and fifth metacarpophalangeal joints exhibited a single sesamoid bone, and they were present in 25.5%, 3.1% and 46.9% of the patients, respectively. Their length and breadth were 0.46 ± 0.10 cm and 0.36 ± 0.07 cm, 0.42 ± 0.14 cm and 0.34 ± 0.17 cm, 0.38 ± 0.06 cm and 0.33 ± 0.04 cm, respectively. The sesamoid bones had a greater incidence in females (
