COVID-19 Vaccine Knowledge, Practice, and Attitudes Among Hemodialysis Patients in Egypt, Kenya, and Cameroon: A Multicenter Study.
Article in Kidney medicine, 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
Rationale & Objective: Patients receiving hemodialysis (HD) are at increased risk of severe coronavirus disease 2019 (COVID-19) and were prioritized for vaccination, yet vaccine hesitancy remains common. We assessed COVID-19 vaccine knowledge, acceptance, and attitudes among patients receiving HD in Egypt, Kenya, and Cameroon and identified factors associated with vaccine acceptance, prior infection, willingness to receive future doses, and postvaccination complications. Study Design: Multicenter cross-sectional survey study. Setting & Participants: Between March 2021 and April 2022, 765 patients receiving maintenance HD and 196 non-dialysis controls were recruited from dialysis centers in Egypt, Kenya, and Cameroon. Predictors: Sociodemographic characteristics, clinical comorbidities, prior COVID-19, sources of vaccine information, and exposure to vaccinated or infected relatives. Outcomes: COVID-19 vaccine acceptance, willingness to receive future doses, prior infection, and post-vaccination complications. Analytical Approach: Structured questionnaires assessed knowledge, practices, and attitudes toward COVID-19 vaccination. Multivariable logistic regression identified factors independently associated with study outcomes. Results: Vaccine acceptance was lower among patients receiving HD than nondialysis controls (58.2% vs 96.2%). Fear of side effects was the most common reason for refusal (39.3%). Postvaccination complications were less frequent among patients receiving HD (22.3% vs 44.3%). Hesitancy was more common among women, younger participants, and those with comorbidities or no prior COVID-19. Having vaccinated or previously infected relatives was associated with a greater willingness to receive future doses. Limitations: Cross-sectional design limits causal inference. Nonprobability sampling and unmatched controls may limit generalizability. COVID-19 cases may have been underreported because of limited testing. Conclusions: COVID-19 vaccine hesitancy among patients receiving HD is driven by fear, misinformation, and sociodemographic factors. Targeted education and improved access to reliable vaccine information may help increase uptake in this population.
