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

backgroundOral health decline in later life is linked to poor nutrition, lower quality of life, and higher morbidity. Frailty, operationalized by the Frailty Index (FI), summarizes cumulative health deficits. Whether frailty predicts subsequent deterioration in oral health remains uncertain.

methodsWe analyzed data from the English Longitudinal Study of Ageing (ELSA). Participants aged ≥ 50 years who rated their oral health as “good” at wave 8 and had follow-up at wave 9 were included (n = 5,526). Oral-health decline was defined as a transition from “good” at baseline to “not good” at follow-up. FI was examined continuously and by quartiles. Cox proportional hazards models with progressive adjustment estimated hazard ratios (HRs) and 95% CIs. Linear trend across FI quartiles, restricted cubic splines, and prespecified subgroup/interaction analyses were conducted.

resultsHigher frailty predicted faster oral-health deterioration. In the fully adjusted model, each 1-point increase in FI was associated with a 3% higher hazard (HR = 1.03, 95% CI: 1.02–1.04; P < 0.001). Compared with the lowest FI quartile, HRs were 1.33 (95% CI: 1.00–1.77), 1.58 (1.16–2.14), and 2.26 (2.02–3.70) for quartiles 2–4, respectively (P-trend < 0.001). Spline analyses supported an approximately linear dose–response. Associations were broadly consistent across subgroups defined by age, sex, smoking, drinking, marital status, hypertension, diabetes, COPD, cancer, and depression, with no material effect modification.

conclusionIn a national cohort of older adults in England, greater frailty was independently associated with higher risk of oral-health decline over two years. Integrating oral-health assessment and prevention into frailty screening and management may help mitigate deterioration.
