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
BACKGROUND This retrospective study aimed to radiographically compare injectable platelet-rich fibrin (I-PRF)-enriched bone graft matrix (sticky bone) with conventional particulate grafting during lateral sinus lift procedures performed simultaneously with implant placement in patients exhibiting insufficient posterior maxillary residual bone height. MATERIAL AND METHODS Twenty-four systemically healthy, non-smoking patients who underwent lateral sinus lift surgery between January 2014 and June 2023 were included. Patients were retrospectively allocated into groups according to grafting material: conventional particulate bone graft (group 1, n=12) and I-PRF-enriched bone graft matrix (sticky bone) (group 2, n=12). Radiographic bone height measurements were obtained using panoramic radiographs acquired preoperatively, immediately postoperatively, and at 6 months postoperatively. Measurements were conducted using calibrated digital software. Inter- and intragroup comparisons were analyzed via paired and independent samples t-tests, using a statistical significance threshold of P<0.05. RESULTS Immediate postoperative bone gain was significantly higher in group 1 than in group 2 (11.94 mm vs 10.15 mm; P<0.05). However, bone resorption at 6 months was significantly greater in group 1 than in group 2 (2.61 mm vs 1.07 mm; P<0.05). Bone loss percentage also was significantly higher in group 1 than in group 2 (16.50% vs 7.74%; P<0.05), indicating superior bone preservation in group 2. CONCLUSIONS Although conventional grafting resulted in greater initial bone gain, I-PRF-enriched bone graft matrix demonstrated significantly reduced bone resorption at 6 months. Sticky bone may provide a clinical advantage in bone preservation after sinus lift procedures.
