Correlation between periodontal procedures and aggregate variables of Brazilian States from 2018 to 2023.
Article in Odontology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To investigate the correlations between the percentage of supragingival scaling, planing, and polishing (SSPP) and subgingival scaling and root planing (SRP) by generalist dentists (GD) and periodontists with the aggregate variables of Brazilian Federal Units (FU). This study used aggregated data extracted from the Unified Health System (UHS) and Brazilian Institute of Geography and Statistics. Outcome variables included the total and the percentages of SSPP and SRP procedures of all FU, during 2018-2019, 2020-2021, and 2022-2023. The independent variables collected were: total population number, proportion of white individuals, Gross Domestic Product (GDP), Human Development Index (HDI), coverage of oral health teams in Primary Health Care (PHC), number of Basic Health Units (BHU), Dental Specialist Centers (DSC), and investments made in PHC. Correlation coefficients were estimated between the percentage of procedures and independent variables. A multilevel Poisson regression model verified differences in the total number of periodontal procedures. In total, 42,312,458 SSPP and 29,850,275 SRP procedures were performed between 2018 and 2023. The total number of periodontal procedures decreased significantly during the period of 2020-2021, compared to 2018-2019 (count ratio [CR] = 0.38; 95% confidence interval [95%CI] = 0.31-0.47). Numbers of DSCs were correlated with an increase in the percentage of SSPP (R = 0.571, R = 0.422, R = 0.585) and SRP (R = 0.539, R = 0.540, R = 0.484) across all periods when performed by periodontists. However, greater investments in PHC were correlated with higher percentages of procedures performed by GD.
