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

objectiveThis retrospective study aimed to evaluate differences in cortical and trabecular alveolar bone between normal dentition and edentulous sites across different age and sex groups.

methodsA total of 191 partially edentulous patients who underwent preoperative cone-beam CT (CBCT) were retrospectively analyzed. Cortical bone thickness, cortical bone density, and trabecular bone density were measured at both normal dentition and edentulous sites across six anatomical regions in the maxilla and mandible. Comparisons were made across age groups and sexes, and between paired edentulous and normal sites. Implant outcomes were recorded, and success rates were calculated.

resultsAt normal dentition sites, cortical bone thickness and density significantly declined with age, particularly in the posterior regions. Young females showed higher cortical bone mass than males, though this difference diminished with age. In contrast, trabecular bone density tended to increase with age. Edentulous sites showed significantly reduced cortical thickness, cortical density, and trabecular density compared to normal sites. Among 180 patients with implant placement, the success rate was 98.88%, with failures limited to three male patients.

conclusionThis study revealed heterogeneous alterations in alveolar bone associated with aging, with cortical bone exhibiting more pronounced atrophy than trabecular bone. Despite these variations in bone quantity and quality, implant restoration achieved a high success rate, regardless of the underlying alveolar bone condition.
