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

BACKGROUND AND

objectiveThe anatomy of the craniovertebral junction (CVJ) varies considerably across populations, yet comprehensive Turkish-specific morphometric data remain limited. We aim to establish normative CVJ measurements in Turkish males and females using computed tomography (CT). STUDY

designRetrospective morphological study. MATERIALS AND

methodsA retrospective analysis of CT images from 500 patients (250 females and 250 males, aged 25-40 years) was conducted between January and December 2022. CVJ measurements were obtained, and sex-related differences were assessed.

resultsThe mean atlantodental interval was 1.45 ± 0.01 mm, posterior atlantodental interval 19.35 ± 0.09 mm, McGregor line 79.78 ± 0.21 mm, Chamberlain line 76.95 ± 1.21 mm, McRae line 36.27 ± 0.12 mm, Wachenheim clivus-canal angle 154.65 ± 0.45

conclusionThis study provides a comprehensive CT-based analysis of CVJ measurements in Turkish adults, establishes normative morphometric values, and shows that most parameters exhibit sex-based differences. These population- and sex-specific reference data may be crucial for improving the accuracy of clinical assessments and surgical planning.
