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
purposeTo determine the prevalence of complete type retrotransverse (RTF) and arcuate foramen (AF)'s in a large cohort using three-dimensional (3D) computed images (CT) and explore their correlation with each other.
methodsBetween January 2023 and August 2024, all neck and cervical vertebrae CTs taken in our hospital were scanned retrospectively. It is noted the presence or absence of complete RTF and AF, laterality, gender, and age of those included in the study.
resultsA total of 2000 patients were included in the study, with an equal distribution of females and males. The prevalence of complete AF was 6.4%, 10%, and 16.3% bilaterally, unilaterally, and in total. The prevalence of complete AF was 12% in females and 20.6% in males. The gender prevalence differences of bilateral AF were statistically significant (p < 0.001). The prevalence of complete RTF was 1.8%, 8.9%, and 10.6% bilaterally, unilaterally, and in total. The prevalence of complete RTF was 9.7% in females, and 11.6% in males. The prevalence differences between genders were insignificant (p = 0.173). The ipsilateral prevalence of complete AF and RTF was 0.2%, 0.2%, and 0.4%, respectively, bilateral, unilateral right, and unilateral left.
conclusionsThe complete AF and RTF prevalences in the study group were not uncommon. The prevalence of complete AF and RTF together is quite rare. Complete RTF is more common in elderly patients and on the left side, while complete AF does not show any difference in laterality and age, and is more common in males than in females.
