1 · What the graph read from 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.

2 · The registry

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

backgroundPulp stones are a common manifestation of pulp calcification, and their formation may correlate with systemic metabolic disorders. This study was designed to investigate the prevalence of pulp stones in diabetic patients in Southwest China and quantitatively evaluate the potential correlation between their morphological characteristics and diabetes.

methodsCone-beam computed tomography (CBCT) scans of 240 patients aged 40 to 69 years, including 120 diabetic patients and 120 healthy controls, were evaluated for a total of 5920 teeth. Mimics software was utilized to construct three-dimensional models for the quantitative measurement of pulp stone volume (mm³) and surface area (mm²). Pearson chi-square test, nonparametric tests, logistic regression, and generalized linear model (GLM) were used for statistical analysis.

resultsDiabetic patients exhibited a significantly higher prevalence of pulp stones than non-diabetic individuals (81.67% vs. 52.50%, p < 0.001). Even across different genders, age groups, maxillary and mandibular regions, as well as their respective subregions, the diabetic group consistently demonstrated a higher prevalence rate. Diabetic patients also exhibited larger pulp stone volume (1.85 mm³, IQR = 0.83–4.17 vs. 1.46 mm³, IQR = 0.63–2.62) and surface area (10.05 mm², IQR 5.41–17.53 vs. 7.87 mm², IQR 4.86–12.99) compared to controls (p < 0.05 for both). Diabetes was recognized as an independent risk factor for pulp stones by logistic regression (adjusted odds ratio [aOR] = 2.92, 95% confidence interval [CI] = 2.34–3.63). GLM confirmed diabetes increased pulp stone volume (Exp(B) = 1.38, 95% CI = 1.16–1.63, p < 0.001).

conclusionsDiabetic patients have a significantly higher prevalence of pulp stones, with larger volume and surface area. By enabling precise three-dimensional modeling and measurement of pulp stones, this approach assists dentists in optimizing access cavity preparation and locating canal orifices, thereby providing a concrete basis for formulating informed clinical strategies.
