Health-related quality of life in patients on maintenance hemodialysis: Evidence from southern Iran using EQ-5D-5L and KDQOL-SF.
Article in PloS one, 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
backgroundHemodialysis (HD) is a common treatment for end-stage renal disease (ESRD) but is often accompanied by markedly reduced health-related quality of life (HRQoL). This study aimed to assess HRQoL and its determinants among HD patients.
methodsIn this cross-sectional study, 203 adult HD patients in Bandar Abbas, Iran, were evaluated. HRQoL was measured via the EQ-5D-5 L index, EQ-VAS, and SF-12 physical (PCS) and mental (MCS) component summary scores. Multivariable linear regression models, identified factors significantly associated with HRQoL.
resultsThe mean (SD) EQ-5D-5 L index, EQ-VAS, PCS, and MCS scores were 0.50 (0.47), 64.9 (23.7), 42.3 (8.1), and 42.3 (9.0), respectively. Individuals with higher levels of education demonstrated significantly better EQ-5D-5L index scores (β: 0.24, 95% CI: 0.06 to 0.41 for <6 classes; β: 0.22, 95% CI: 0.03 to 0.40 for 6-12 classes; β: 0.33, 95% CI: 0.13 to 0.52 for >12 years). Being divorced/widowed (β: -20.5, 95% CI: -35.7 to -5.3) or retired/disabled (β: -22.5, 95% CI: -41.6 to -3.3) showed a statistically significant association with reduced EQ-VAS scores. Having supplemental insurance was significantly linked to higher PCS scores (β: 2.4, 95% CI: 0.1 to 4.6), whereas current tobacco use was linked to lower MCS scores (β: -3.7, 95% CI: -7.4 to -0.02). A duration of dialysis ≥5 years was significantly associated with lower EQ-5D-5 L index scores (β: -0.17, 95% CI: -0.31 to -0.04). Comorbidities, age, and sex were not significantly associated with any of the HRQoL measures.
conclusionHRQoL among HD patients in southern Iran was markedly reduced and influenced by socioeconomic, lifestyle, and treatment-related factors. Enhancing patient education, expanding insurance coverage, addressing gaps in social support, and incorporating lifestyle interventions-such as smoking cessation-may be associated with modest improvements in HRQoL outcomes in this population.
