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

Background: Implant stability is an important determinant of successful osseointegration and long-term clinical outcomes. Although novel implant designs continue to emerge, independent multicenter clinical evidence evaluating longitudinal implant stability patterns remains limited. Aim: To evaluate longitudinal implant stability patterns of a novel Grade 23 titanium dental implant system using resonance frequency analysis (RFA) across multiple clinical time points. Materials and methods: This multicenter prospective observational study included 230 patients receiving 295 implants across nine academic centers. Implant stability quotient (ISQ) values were recorded at implant placement, second-stage surgery, impression making, and prosthesis trial. Descriptive statistics and non-parametric analyses (Friedman, Wilcoxon signed-rank, and Mann-Whitney Results: ISQ values remained generally high throughout the observation period, with mean ISQ values ranging from 73.06 ± 11.66 at implant placement to 75.07 ± 8.23 at the prosthesis trial stage. Mandibular implants demonstrated higher ISQ values than maxillary implants during the early healing stages ( Conclusion: Within the limitations of this multicenter observational study, the evaluated implant system demonstrated favorable longitudinal ISQ trends during early healing. However, long-term controlled clinical studies incorporating comparative implant systems, radiographic bone level assessment, and extended follow-up are required before definitive clinical recommendations can be established.
