Timing of alveolar bone surgery as a predictor of guided bone regeneration success: results of a retrospective cohort study.
Article in Journal of medicine and life, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 physiological condition of bone prior to regenerative procedures has received little attention, with concerns more often related to technical and biomaterial issues. The primary aim of the study was to test whether pathophysiological changes in bone following tooth extractions or other alveolar bone surgery have an additional impact on bone growth in guided bone regeneration (GBR) with collagen membranes. A total of 33 consecutive patients with vertical and horizontal atrophy of the alveolar ridges, comprising 70 dental sites, treated with staged GBR using collagen membranes and a resorbable graft material, were analyzed in terms of the specific results of the procedure. The effect of defect morphology and recent bone surgery on the critical dimensions of the alveolar ridge was assessed by superimposing serial cone-beam computed tomography (CBCT) images before the augmentation procedure and after the bone healing period. Complex defects and recent bone surgeries, not older than 6 months, showed the greatest increase in crest width: 6.42 mm (
