Prevalence of Periodontitis and Methodological Aspects of the 2018 EFP/AAP Classification-The Study of Health in Pomerania (SHIP-TREND).
Article in Journal of clinical periodontology, 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
aimTo estimate the prevalence of periodontitis and highlight methodological issues using the Application of the 2018 Periodontal Status Classification to Epidemiological Survey Data (ACES) framework. MATERIALS AND
methodsWe used data from the population-based Study of Health in Pomerania (SHIP-TREND; age 20-84 years). Periodontal status was recorded using a half-mouth protocol. We estimated the prevalence of periodontitis, evaluated changes in the assignment of stages to combinations of available complexity factors, associated periodontal status with 7-year tooth loss and illustrated agreement with the Centers for Disease Control and Prevention/American Academy of Periodontology (CDC/AAP) classification.
resultsThe total prevalence of periodontitis was 78.6%; 18.0% and 17.4% were Stage III and Stage IV, respectively. Grade C was exhibited by 49.1% of Stage III cases and 37.8% of Stage IV cases. Assignment of stage changed only marginally when complexity factors were considered in addition to interdental clinical attachment levels. Three percent of Stage IV cases and 15.2% of non-classified cases became toothless. Adjusted incidence rates for tooth loss were 3.60 for Stage III cases, 6.55 for non-classified cases and 8.69 for Stage IV cases. Severe cases (CDC/AAP) corresponded primarily to Stage III (42.9%) and Stage IV (53.0%) cases.
conclusionsFor public health purposes, caution should be exercised when translating the periodontitis prevalence according to the ACES framework into treatment requirements. Furthermore, complex and effective interventions are required for non-classified and Stage IV cases in order to prevent tooth loss and edentulism.
