Examining factors associated with catheter-defined unplanned dialysis initiation: a UK Renal Registry analysis.
Article in Clinical kidney journal, 2026. 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
Background: In the UK, nearly half of patients with end stage kidney disease (ESKD) who initiate dialysis do so in an unplanned manner. A reduced quality of life, increased number of hospitalisations, and higher rates of mortality are just a few of the consequences of unplanned dialysis initiation (UDI). Our study examined factors associated with UDI in patients with ESKD in England, focusing on the effects of ethnicity and late presentation (LP). Patients and methods: We conducted a retrospective cohort study using data from the UK Renal Registry on 26 512 adult patients initiating dialysis between 2019 and 2023. UDI was defined as starting dialysis via a tunnelled or non-tunnelled line. We ran univariable and multivariable (multilevel) logistic regression analyses to examine risk factors of UDI, then tested for interactions between ethnicity and other key risk factors. Results: Just under half of the population had a UDI (49%), with Black and 'Other' patients having increased odds (1.36 and 1.29, respectively) of having a UDI than White patients, after adjusting for age. Unsurprisingly, the age-adjusted analyses also showed that LP and UDI were strongly associated (odds ratio (OR) 8.03, 95% confidence interval (CI) 7.38-8.74). Among late presenters, Asians had lower odds of UDI (OR 0.77, 95% CI 0.61-0.99) than Whites. For non-late presenters, the odds of UDI were higher in Asians (OR 1.18, 95% CI 1.09-1.28), Blacks (OR 1.47, 95% CI 1.32-1.64), and 'Other' (OR 1.30, 95% CI 1.08-1.57) compared to Whites (ethnicity and LP interaction Conclusions: Our study highlighted ethnicity as an important risk factor for UDI. Further, timing of presentation appears to alter ethnic differences in UDI.
