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

Objectives: To analyze the posterior mandible bone ridge shape in relation to gender and tooth loss. Focusing on the accompanied changes and variations in lingual concavities. Methods: 406 cone-beam computed tomography (CBCT) images with dentulous and edentulous 1st and/or 2nd molars (206 females and 200 males, aged ≥20) were examined. Mandibular morphology was classified into U type (undercut), P type (parallel), and C type (convex). The study examined the ridge morphology and dimensions. Lingual concavities angle, area, and the concavity position were measured/reported. Results: U type bone shape was the most common bone shape 64.1%, then P type was 24.8%, while C type was 11.2 %. U ridge was more frequent in 2nd molar compared to the 1st molar regions ( Conclusion: The U type ridge was the most common in the studied population, occurring more often in the second molars region. Bone ridge and lingual concavities dimensions were varied by gender, tooth loss, and specific tooth. Lingual concavities were significantly related to MC level.
