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
Background: Marketed toothpastes vary in the extent to how much abrasive wear they cause to dentin. New abrasive particles in a dentifrice should be evaluated since there they can be at risk of abrasion to dentin and root surfaces. Aim: The aim of this in vitro study was to evaluate abrasive dentin wear and surface roughness after brushing with whitening toothpaste containing zirconia at four different concentrations. Material and method: This study tested 40 extracted human teeth. After crown removal, root dentin samples were randomly divided into four experimental groups based on zirconia toothpaste concentration: Group A (10 samples) brushed for 5 min with 0.5 % zirconia toothpaste, Group B (10 samples) with 1 %, Group C (10 samples) with 2 %, and the last 10 samples with 5 %.Before brushing, specimens were weighed three times using a precision analytical scale and measured with a Profile Projector. After completing the brushing cycles, surface roughness was measured to evaluate the differences after brushing. Results: The Kruskal-Wallis test showed no significant difference in the weight of samples at 0.5 %, 1 %, and 2 % toothpaste concentrations. However, at the 5 % toothpaste concentration, there was a significant difference in sample weight measurements (P < 0.05). The mean roughness difference in the three lower concentrations indicated no significant statistical difference, but with the 5 % toothpaste, there was an increase in average dentin roughness (P < 0.05). Conclusion: Results showed that percentage ≤2.0 % of zirconium powder added in a toothpaste, can lead to dentin minimal wear and better roughness by polishing effect. Toothpaste containing 5 % zirconia showed an abrasive effect on dentin and increased surface roughness.
