Using revised oral assessment guide to assess association between oral health and mortality in older inpatients: a single-center observational cohort study.
Observational study in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeFor older adults, oral health represents a critical component of overall health; nevertheless, oral health is often neglected in older acute inpatients. We implemented a retrospective cohort study to assess oral health in older inpatients by using the revised oral assessment guide (ROAG) and examined the associations of oral health and mortality.
methodsThe study was executed in a 35-bed geriatric ward. The study sample comprised patients aged 65 years or older, hospitalized with an acute condition. The oral health of the patients was assessed by trained nurses using revised oral assessment guide (ROAG). Data were collected during hospitalization from admission through discharge. Medical records were assessed to glean medical and demographic data. The mean follow-up time was 1.9 (SD 1) years. Mortality data were collected from a national population register. The age adjusted Charlson comorbidity index (ACCI) was employed to assess comorbidities. Cox regression was executed to identify associated factors.
results360 patients were enrolled in the study. The mean ROAG score was 11.1 (SD 2.5), and 49.2% of the patients had a ROAG score greater or equal to 11. The oral problems that were most common were related to the teeth or dentures (74.2%), followed by problems related to the gums (32.8%). Significant associations between oral health problems and various patient characteristics were observed. The risks of overall mortality (HR = 1.67, P =.003) and 2-year mortality (HR = 1.72, P =.004) were significantly higher among patients with ROAG scores of ≥ 11 than among those with ROAG scores of < 11, after adjustment for potential confounders.
conclusionAmong older acute inpatients, the prevalence of oral health problems was relatively high, and poor oral health was an independent mortality predictor. These findings highlight the importance of oral health care in older adults.
