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
Regenerative combination therapies are increasingly used in periapical surgery to enhance osseous healing. This case study examines the clinical and radiographic outcomes of platelet-rich fibrin (PRF) and simvastatin, both combined with bovine bone xenograft, in the treatment of periapical defects. Two patients with persistent periapical pathology requiring surgical intervention were treated using different regenerative approaches and demonstrated comparable preoperative clinical and radiographic characteristics. Clinical outcomes were assessed using the Universal Pain Assessment Tool. At the same time, radiographic healing was evaluated using cone-beam computed tomography, analyzed according to the modified Penn 3D criteria over a 4-year follow-up period. Both PRF and simvastatin, when combined with a xenograft, demonstrated the ability to promote and guide bone regeneration.
