Oral health care among dialysis patients in France and impact on survival.
Article in Journal of nephrology, 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
backgroundOral diseases have been shown to be risk factors of Chronic Kidney Disease (CKD) progression and may also be associated with poorer survival. The aim of this study was to describe oral care of dialysis patients in France and to assess its impact on their survival.
methodsWe conducted a retrospective cohort study including all patients on dialysis in France between 2015 and 2020. Data were collected from the French REIN registry and matched with the National Health Data System. Factors associated with the probability of receiving oral care treatments were explored using a logistic regression model. The survival of incident dialysis patients was modeled using a Cox model.
resultsAmong the 101,942 prevalent patients included in our sample, 32.5% received oral care treatment over the 6-year study period. Average annual adoption was 18.7% (versus 43% in the general French population) with regional variations. Male gender, overweight, dialysis treatment < 3 and > 6 years, and being on the transplant waiting list were associated with greater oral care treatment. Oral care treatment was associated with a lower risk of death (weighted hazard ratio (HR) 0.53 [0.51-0.55], adjusted HR 0.50 [0.48-0.52] 95% confidence interval (CI)).
conclusionDialysis patients in France undergo a low level of oral care treatments. Patients' characteristics and regional practices appear to influence this. Oral care treatments seem to have a positive impact on survival.
