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

Objectives: This pilot study aimed to determine whether adjunctive photobiomodulation (PBM) alters dental plaque microbiota and clinical parameters in periodontitis patients during orthodontic retention. Methods: Six stage IV, grade C periodontitis patients entering orthodontic retention were enrolled in this split-mouth study. One arch side received monthly PBM therapy (GaAlAs diode laser) for six months; the contralateral side received sham irradiation. Periodontal examinations were performed. Supragingival and subgingival plaque samples were evaluated at appliance removal (T Results: No significant differences were observed in periodontal clinical parameters between PBM and placebo sites at any time point ( Conclusion: Adjunctive PBM did not significantly alter overall plaque microbial community structure or clinical periodontal parameters. However, a few periodontitis-associated genera showed nominal, exploratory differences. These hypothesis-generating signals warrant confirmation in adequately powered trials.
