Plaque Reduction Efficacy of an Advanced Electric Toothbrush Compared with a Manual Toothbrush Among 6- to 10-Year-Old Children: Results From a 4-Week Randomised Controlled Trial.
Trial report in International journal of paediatric dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAn advanced oscillating-rotating (OR) electric toothbrush was developed to help improve plaque control for paediatric patients.
aimTo assess plaque reduction efficacy of an advanced OR electric toothbrush compared with a manual toothbrush among children.
designThis was a 4-week randomised, controlled, two-treatment, parallel-group, examiner-blind clinical study. Sixty children, 6-10 years of age, were randomly assigned to a test group: 1) Advanced OR electric toothbrush (Oral-B iO2 with Gentle Care brush head) or a control group: 2) Manual toothbrush (Paro Junior Soft). Both groups brushed twice daily with a fluoridated dentifrice. Plaque was assessed at baseline and 4 weeks using the Turesky modification of the Quigley-Hein Plaque Index. Data were analysed with ANCOVA.
resultsSixty participants were enrolled (30/group); mean (SD) age 7.7 (±1.33) years. Fifty-eight children completed the trial. At week 4, the test group had 51% greater whole mouth plaque reduction compared with the control group (0.67 versus 0.44; p = 0.003). The test group also had statistically significantly greater plaque reductions (p ≤ 0.021) than the control group in lingual, buccal, approximal, and molar subregions, ranging from 42%-64% greater.
conclusionThe advanced OR electric toothbrush produced significantly greater plaque reductions compared with a manual toothbrush among a paediatric population.
