Glycemic control and number of natural teeth: analysis of cross-sectional Japanese employment-based dental insurance claims and medical check-up data.
Article in Diabetology international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
aimDiabetes mellitus is a well-known risk factor for onset and progression of periodontal disease. However, the continuous relationship between glycemic control and the number of natural teeth has not been well characterized in large-scale studies. We aimed to determine whether the glycated hemoglobin A1c (HbA1c) level and fasting plasma glucose (FPG) are associated with the number of natural teeth.
methodsA cross-sectional study: A database comprising employment-based health insurance claim and medical check-up data from 706,150 participants between April 2015 and March 2016 in Japan. The exclusion criteria included missing data regarding dental receipts, number of natural teeth, HbA1c, smoking status, and age < 20 years. Ultimately, 233,567 individuals were analyzed. The participants were allocated to five groups according to their HbA1c and three groups according to their FPG, and then the number of natural teeth were compared.
resultsHigher HbA1c was associated with fewer teeth in participants ≥ 30 years of age (
conclusionsGlycemic control is strongly associated with the number of natural teeth in the real-world setting. Furthermore, there are continuous relationships of HbA1c and FPG with number of natural teeth including individual with impaired fasting glucose. These data emphasize the importance of glycemic control and appropriate oral care for the protection against tooth loss.
