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

backgroundThis study aims to assess the oral health status and unmet restorative and prosthetic needs of older adults in La Araucanía Region, Chile, with a particular focus on the influence of sociodemographic factors and ethnic ancestry. The goal is to provide data to inform health policies and programmes tailored to older adults.

methodsA cross-sectional study was conducted involving 157 dentate older adults aged 60 and older from five municipalities in La Araucanía Region, Chile. Participants were recruited using convenience and snowball sampling methods. Evaluations were carried out in remote settings via a mobile dental clinic, where extensive data were collected. Participants' sociodemographic information, medical conditions, and oral health status were assessed, including the Decayed, Missing, and Filled Teeth (DMFT) index and periodontal status. Linear and logistic regression analyses were used to explore associations between variables.

resultsThe mean age of participants was 70.2 years, most being female (73.2%). The average DMFT score was 23.9 teeth, dental caries experience was higher in females (24.4 vs. 22.0; p < 0.01), and in those not having tertiary education compared to those who did (24.2 vs. 21.2; p < 0.01). Participants had 32.2% of their restorative needs unmet, with males (49.6% vs. 26.4%; p < 0.01) and those of Mapuche ancestry showing higher proportions of unmet needs (48.1% vs. 25.6%; p < 0.01). 54.1% of participants had unmet prosthetic needs. Participants living in larger municipalities had lower unmet prosthetic needs compared to those living in other municipalities (OR = 0.13; 95% CI:0.04-0.49). All participants showed some level of periodontal involvement, with living arrangements (lived alone (OR = 4.73; 95%CI:1.48-15.13)) and multimorbidity (OR = 1.50; 95%CI:1.09-2.05) being predictors of periodontitis. Only 15.1% required urgent dental treatment.

conclusionsThis study provides insights into the oral health challenges faced by older adults living in remote areas of Chile, highlighting significant disparities associated with sociodemographic factors. The findings underscore the need for integrated healthcare models and targeted interventions to address unmet needs and improve oral health outcomes in this population.
