Variability in the utilization of preventive dental services among the underserved population of Indiana.
Article in PloS one, 2025. 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
objectivesTo explore the variability of utilization patterns of preventive dental services among diverse demographic groups in the state of Indiana.
methodsThis study utilizes a retrospective data analysis approach to examine the preventive dental services utilization among patients treated by senior-year dental students (D4 students) during their community-based clinical rotations at Federally Qualified Health Centers and private practices, affiliated with Indiana University School of Dentistry. The data were extracted from daily patient reports submitted by D4 students for every patient they examined during their rotations, via RedCap. Descriptive statistics and generalized linear modeling using main effects were performed to identify the utilization of different preventive services across urbanization stratification and demographic variables among the included participants.
resultsThere was a statistically significant (p < 0.001) distribution of all dental preventive services according to demographic characteristics, viz. age, ethnicity, location (rural or urban), primary language spoken, and insurance status. There were 30.39 times higher odds of utilizing preventive dental services in a rural zip code compared to an urban zip code. Individuals with multicultural ethnicities (OR= 0.91, 95% CI: 0.54, 1.53) were less likely to utilize preventive dental services than the "Other" category, although the value was not significant (p = 0.72). Also, the younger age group (less than 17 years) was more likely to utilize preventive dental services than the older age group (p < 0.001).
conclusionsInequities in the utilization of preventive dental services were identified among the underserved population of Indiana, according to demographic characteristics.
