Clinical Outcomes of a Digital Companion in Periodontal Care: A Randomised Controlled Trial.
Trial report in Journal of clinical periodontology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimTo evaluate the efficacy of a digital health companion app as an adjunct to systematic periodontal therapy.
methodsSeven German university dental centres conducted this multi-centre randomised controlled trial. Adults with periodontitis (n = 194) were assigned to standard periodontal care with or without the Paro-ComPas app. The primary endpoint was the gingival bleeding index (GBI) at baseline, re-evaluation and during supportive periodontal care. Secondary outcomes included plaque and bleeding on probing. Confirmatory analyses used longitudinal mixed-effects regression. Exploratory analyses examined clinical outcomes by app usage cluster.
resultsOf the 180 participants, 148 completed the trial. Both groups showed substantial clinical improvements. The unadjusted between-group difference favoured the control group [7.70 pp (0.55; 14.85) at T0-T2]; the adjusted analysis showed no significant difference in the primary endpoint (1.56 pp; p = 0.352) or in secondary endpoints. Implementation fidelity was suboptimal. Exploratory analyses revealed that moderate app users achieved significantly greater plaque reductions compared to low users (-14.95 pp; p = 0.034).
conclusionsThis trial found no significant benefit of a digital companion app as an adjunct to systematic periodontal therapy. Low baseline inflammation, incomplete intervention delivery and inter-examiner variability likely limited detection of small effects. Exploratory findings suggest potential benefits among moderately engaged users.
