Periodontitis Prevalence in a West African Sub-Population Using Two Definitions: A Cross-Sectional Study in Ouagadougou (Burkina Faso).
Article in Oral health & preventive dentistry, 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
purposeThis study evaluated prevalence, severity and risk indicators of periodontitis among urban West African adults using CDC/AAP 2012 and EFP/AAP 2018 criteria. MATERIALS AND
methodsA cross-sectional study among adults attending four public dental centers in Ouagadougou, Burkina Faso was conducted. Sociodemographic and risk factors were collected by interview, and full-mouth periodontal exams were performed at six sites per tooth. Both CDC/AAP 2012 and EFP/AAP 2018 definitions were applied. The performance of the EFP/AAP criteria was compared with CDC/AAP as the reference.
resultsA total of 749 participants (mean age: 34.32 ± 11.51 years; 52.34% female) were included. The prevalence of periodontitis was 71.83% using EFP/AAP criteria (stage I: 16.02%; stage II: 24.57%; stage III/IV: 31.25%) and 56.21% with CDC/AAP (mild: 6.28%; moderate: 38.45%; severe: 11.48%). Compared with CDC/AAP, EFP/AAP showed high sensitivity (99.29%) but low specificity (28.96%), with a positive predictive value of 64.21% and negative predictive value of 96.94%. Increasing age (CDC/AAP: OR = 1.03, 95% CI: 1.01-1.05, p = 0.001 | EFP/AAP: OR = 1.03, 95% CI: 1.00-1.07, p = 0.040) and smoking (CDC/AAP: OR = 2.78, 95% CI: 1.12-6.89, p = 0.028 | EFP/AAP: OR = 2.24, 95% CI: 1.03-4.86, p = 0.040) were consistently associated with higher odds of periodontitis.
conclusionPeriodontitis was highly prevalent in this urban West African population, with advanced disease affecting up to one-third of adults. The EFP/AAP classification identified more cases but showed lower specificity, potentially overestimating disease burden in settings with high prevalence but predominantly moderate disease.
