Prevalence and clinical correlates of peripheral artery disease in patients undergoing hemodialysis: a cross-sectional study from Palestine.
Article in BMC nephrology, 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
backgroundPeripheral artery disease (PAD) is a common but underrecognized complication among patients with end-stage renal disease (ESRD) receiving hemodialysis. PAD contributes substantially to morbidity and mortality, yet data from Palestine are lacking. This study aimed to estimate the prevalence of PAD and examine its association with clinical and laboratory characteristics in hemodialysis patients.
methodsA cross-sectional study was conducted between February and November 2023 at the dialysis center in a large tertiary accredited teaching hospital, the main referral center in the northern West Bank, Palestine. A total of 278 patients undergoing regular hemodialysis were enrolled. PAD was diagnosed using the ankle–brachial index (ABI) measured by handheld Doppler ultrasound; ABI ≤ 0.90 indicated PAD. Demographic, clinical, and laboratory data were collected from patient interviews and medical records. Multivariable logistic regression was used to identify factors associated with PAD and to estimate adjusted odds ratios with 95% confidence intervals.
resultsPAD was detected in 150 of 278 patients (54%). The mean age was 57 ± 16 years, and 176 (63.3%) were male. Hypertension was present in 236 (84.9%), diabetes mellitus in 147 (52.9%), and cardiac disease in 85 (30.6%). PAD was significantly associated with older age (p = 0.01), longer dialysis duration (p = 0.03), hypertension (p = 0.025), diabetes (p = 0.023), cardiac disease (p = 0.008), and lower serum phosphorus levels (p = 0.03). No significant associations were observed with gender (p = 0.448), smoking (p = 0.836), prior myocardial infarction (p = 0.074), stroke (p = 0.170), physical activity (p = 0.688), vascular access type (p = 0.688), duration of hypertension (p = 0.281), or duration of diabetes (p = 0.165). In a multivariable logistic regression model, dialysis duration remained significantly associated with PAD (adjusted OR 1.08 per year, 95% CI 1.01–1.16, p = 0.031).
conclusionsPAD prevalence was high among hemodialysis patients in this Palestinian cohort, and longer dialysis duration emerged as a significant correlate of PAD. Routine ABI screening—particularly in patients with longer dialysis vintage—may enable earlier detection and management of PAD, potentially reducing adverse cardiovascular outcomes. Further longitudinal studies are warranted to identify causal pathways and inform preventive strategies.
