Background: Risk visualizations are often employed to support risk communication. However, their effectiveness in communication of single absolute risks remains unclear. We investigated the effectiveness of risk visualizations in conveying verbatim knowledge of single absolute risks among the general population.

Methods: Randomly sampled members of the general Dutch population completed four basic risk conversions from percentages to natural frequencies and vice versa. By random investigator-blinded allocation, these conversions were supported by either icon arrays, pie charts, bar graphs or no visualization. Verbatim risk knowledge was scored as the number of conversions completed correctly.

Results: 393 subjects were included. Overall, 60% of respondents answered all four questions correctly. Risk format (percentages vs. natural frequencies, p = 0.677) and risk magnitude (p = 0.532) were not associated with verbatim risk knowledge score. Younger age (p = 0.001) and higher education level (p < 0.001) were independently associated with higher scores. The use of risk visualizations was not associated with higher scores (OR = 1.08; 95% confidence interval: 0.69-1.69; p = 0.745). All three forms of risk visualization were equally ineffective. These findings held when stratifying by risk format, risk magnitude and user preference for a certain form of risk visualization. There were no significant interactions with age or education level.

Conclusion: Risk visualizations did not improve conveyance of verbatim knowledge of single absolute risks, irrespective of age, education level, risk magnitude, risk format and form of risk visualization. Risk visualizations may therefore be less suitable for settings in which detailed conveyance of single absolute risks is the main objective, although their effect on user experience and perception of risk communication and subsequent patient activation and participation remains to be elucidated.

The incidence of inflow and drain pain and associated risk factors for patients on peritoneal dialysis.

BMC Nephrol

Background: The high prevalence and prolonged duration of inflow pain and drain pain experienced by peritoneal dialysis (PD) patients following PD catheter implantation impact their quality of life. However, there is limited data on the frequency and predisposing factors of these pains in the Chinese population undergoing peritoneal dialysis.

Methods: This study encompassed individuals who underwent peritoneal dialysis catheter implantation at our institution from September 1, 2023, to March 31, 2024.

Intracellular dark endothelial spots detected using specular microscopy are associated with graft failure after Descemet's membrane endothelial keratoplasty.

Graefes Arch Clin Exp Ophthalmol

January 2025

Division of Ophthalmology, Department of Visual Sciences, Nihon University School of Medicine, 30-1 Oyaguchi-kamicho, Itabashi-ku, Tokyo, 173-8610, Japan.

Purpose: To investigate the correlation between intracellular dark endothelial spots (IDESs) detected by specular microscopy and the incidence of graft failure after Descemet's membrane endothelial keratoplasty (DMEK).

Methods: We reviewed 100 consecutive DMEK patients performed by a single surgeon at two centres between January 2015 and July 2022. Central corneal thickness was evaluated using anterior segment optical coherence tomography (SS-1000; Tomey, Aichi, Japan), and endothelial cell density was measured using specular microscopy.

Background: We aimed to assess impairments on health-related quality of life, and mental health resulting from Retinal artery occlusion (RAO) with monocular visual field loss and posterior circulation ischemic stroke (PCIS) with full or partial hemianopia using patient-reported outcome measures (PROMs).

Methods: In a prospective study, consecutive patients with acute RAO on fundoscopy and PCIS on imaging were recruited during their surveillance on a stroke unit over a period of 15 months. Baseline characteristics were determined from medical records and interviews.

Background: The dietary intake of hospitalised patients is often compromised during hospitalisation, which can be a causal factor for hospital malnutrition. This is considered a public health problem worldwide and is associated with an increased risk of other complications.

Objectives: Our objective was to determine the dietary intake of hospitalised individuals and if the prescribed diet influences it.
