Caries experience among children and adolescents from a longitudinal Swedish national registry study over a 10-year period.

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
objectiveTo identify caries experience in two groups of children and adolescents using longitudinal data from the Swedish Quality Registry for Caries and Periodontal Diseases (SKaPa). MATERIAL AND
methodsData from two groups (10- and 20-year-olds), 165,365 individuals, were observed retrospectively for 10 years. Using a three-trajectory caries model (3-TCM), individuals were assigned according to their caries development as: high (15%), moderate (45%), or low (40%). Caries experience was expressed using the decayed and filled surfaces (DFS) and dfs indices. The specific affected caries (SaC) index and a point prevalence measurement at age 6 years (PP-6) were also analyzed.
resultsOver the observation period, significant differences were discovered between all three trajectories within the oldest group (20-year-olds). The mean DFS increase was significantly elevated for the high trajectory compared with the lower trajectories, 7.9 ± 10.2, 3.3 ± 2.9 and 0.2 ± 0.5 for the three trajectories respectively. In the youngest group (10-year-olds), the high trajectory combined with the SaC and PP-6 provided further information of those with the highest caries experience.
conclusionsThe 3-TCM identified individuals with high caries experience in the permanent dentition; but to properly elucidate caries experience in the primary and mixed dentitions, a combination with other indices was needed.
