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

aimThere is a need for greater understanding of the average brushing time among individuals. Since the average brushing time remains unclear, this study involves a systematic review to assess this aspect of oral hygiene practices and how it has evolved over the years. MATERIAL AND

methodsThe PubMed-MEDLINE and Cochrane-CENTRAL databases were searched from their inception until January 22, 2025, to identify relevant studies. Eligible clinical trials included healthy adults who performed self-brushing. The primary outcome was the average duration of a toothbrushing exercise in seconds/min, with an 'a priori' distinction made between PTB and MTB users. A secondary outcome assessed the correlation between publication year and brushing duration. Sub-analyses differentiated between powered toothbrush (PTB) and manual toothbrush (MTB) users.

resultsTwelve eligible papers were retrieved, providing 16 evaluations with considerable variability in clinical and methodological design. Fourteen evaluations involved MTB users, and two involved PTB users. The study found that uninstructed adults (≥ 18 years) brush their teeth with an MTB for an average of 87 s. Notably, with moderate strength in the observation, there is a trend that brushing duration among MTB users appears to increase over publication years. PTB users averaged 143 s of brushing time.

conclusionWithin the limitations of the present study design, there is moderate certainty that the average MTB toothbrushing duration among uninstructed adults is approximately one and a half minutes, with a trend suggesting an increase in brushing duration over the years. This duration falls short of the recommended guidelines, whereas PTB users brush for over 2 min on average.
