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
objectiveThis study analyzed trends in tooth loss and caries severity among adults and older adults from 2003 to 2023.
methodsAn ecological study using secondary data from the three national oral health Surveys (SB Brasil 2003, 2010, and 2023) in 43 municipalities that participated in all editions. The analysis of trends in caries severity and tooth loss among adults (35-44 years) and older adults (65-74 years) was performed using structural equation modeling.
resultsAmong adults, a significant association was observed between higher illiteracy rates and increased the decayed, missing, and filled teeth index (DMFT) (β=+0.309; p<0.001). On the other hand, greater coverage by oral health teams and private dental plans were associated with a reduction in these outcomes (β=-0.040 p<0.001 and β=-5.527 p<0.001, respectively). The associations were less evident but pointed in the same direction among older adults regarding illiteracy rates and private dental plan coverage, where the estimated coefficients showed lower magnitude and significance, indicating moderation of contextual effects and stability of the indicators over time.
conclusionThe study confirmed a downward trend in tooth loss and DMFT between 2003 and 2023, pronounced in adults and to a lesser extent in older adults in Brazil. The latter are particularly vulnerable to rapid deterioration in oral health, requiring individualized analyses in future studies and the targeting of efforts by policymakers and implementers.
