Impact of Anaemia on Functional Status in Patients with Chronic Heart Failure.
Article in Juntendo medical 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
Objectives: Chronic heart failure (CHF) restricts daily functioning and quality of life. Anaemia is frequent in CHF and can impair functional outcomes. This research evaluated the effectiveness of anaemia on functional status among Pakistani CHF patients. Materials and Methods: This cross-sectional study comprised 310 patients aged 18 years and above who attended outpatient clinics and community health centres in Islamabad and Rawalpindi. The structured questionnaire was used to gather data on demographics, self-reported anaemia, and medical history. Functional status was assessed using the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Descriptive statistics, chi-square, t-tests, correlation, two-way ANOVA, and multiple regression were analysed. Results: 239 respondents (77%) were anaemic. The KCCQ-12 scores (30.9 ± 3.9) were lower in anaemic patients (34.1 ± 3.2), and there was an inverse relationship between functional status and anaemia (r = -0.338, p < 0.001). There were significant effects of anaemia (p < 0.001), age (p < 0.001), and both (p < 0.001) in two-way ANOVA, with older anaemic patients more impaired. Regression revealed that anaemia (B = -2.10), age (B = -1.25), female gender (B = -0.95), comorbidities (B = -0.48), and smoking (B = -0.65) were the predictors of poor functional status (p = 0.05). Conclusions: Anaemia is ubiquitous among CHF patients in Pakistan and closely associated with diminished functional capacity, especially in the elderly. Anaemia screening and treatment should be part of CHF management to enhance the quality of life.
