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

The goal of this paper was to determine the efficacy of the surgical treatment of two-wall peri-implant defects filled with L-PRF/xenograft block in the reduction of peri-implant marginal bone levels after 12 months. Ten patients with two-wall peri-implant defects were included. Patients received presurgical treatment followed by a surgical reconstructive intervention with bone blocks obtained by mixing bovine origin xenogeneic bone graft grains with L-PRF membranes. Patients were followed up at 3, 6, 9, and 12 months for oral hygiene and disease relapse evaluation and assessment of the primary outcome marginal bone levels (MBL) and clinical outcome variables such as probing depth (PD), bleeding on probing (BOP), and mucosal recession. Data was analyzed for changes between baseline and the 6- and 12-month follow-ups. Mean MBL was 5.1 ± 1.7 mm and 1.58 ± 0.92 mm at baseline and 6 months after the procedure, indicating a statistically significant decrease (
