Efficacy of sonic versus manual toothbrushing after professional mechanical plaque removal: A 6-month randomized clinical trial.
Trial report in International journal of dental hygiene, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimThe aim of this study was to compare the efficacy of two brushing methods (manual vs. sonic) in terms of plaque control after a session of professional mechanical plaque removal (PMPR).
methodsSubjects with gingivitis underwent a session of PMPR and were randomly assigned to sonic (SB) or manual brushing (MB). Oral hygiene instructions were provided at baseline (BL), 2 (T0a), 4 (T0b) and 6 weeks (T1) and 6 months (T2). Plaque Index (PI), Gingival Index (GI) and bleeding on probing (BoP) were measured at BL, T1 and T2. The proportion of sites with PI, GI and BoP was modelled at site level using a negative binomial regression fitted via generalized linear mixed model accounting for intra-patient correlation.
resultsThirty-two subjects were selected, 16 assigned to each group and 31 completed the study. PI, BoP and GI were comparable at BL. At T1, PI was successfully maintained at 6.21% for SB and 22.81% for MB, while at T2 reached 11.34% for SB and 28% for MB, favouring the SB group (p < 0.001). GI and BoP were significantly lower in the SB group at T1, with a BoP reduction for SB about 3 times higher than MB (p < 0.001). These parameters then levelled at T2 between the groups, with BOP reaching 0.14% versus 0.05% (p = 0.356) and GI 1.75% versus 3.52% (p = 0.020).
conclusionSonic brushing seemed to maintain a lower PI score compared to a manual brush at 6 months. BoP and GI resulted comparable.
