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
Background: The prognostic role of thyroid nodules (TNs) in patients with heart failure with reduced ejection fraction (HFrEF) complicated by anemia and hyperuricemia (HUA) remains unclear. This study aimed to investigate the association of TNs with cardiovascular comorbidity burden and long-term prognosis in this high-risk population. Methods: A retrospective cohort of 185 inpatients with HFrEF, anemia, and HUA (2018-2022) was divided into TN (n=94) and non-TN (n=91) groups based on ultrasound findings. Baseline characteristics, laboratory parameters (thyroid function, coagulation), and psychological status (Hospital Anxiety and Depression Scale, HADS) were compared. The primary composite endpoint included all-cause mortality, heart failure rehospitalization, and cardiovascular events. Multivariable logistic and Cox regression analyses identified factors associated with TNs and prognosis. Results: The TN group had higher prevalence of coronary heart disease (65.9% vs 31.8%), atrial fibrillation (71.3%vs 27.5%), and depression scores (8.32 vs 6.02). Logistic regression identified depression (OR = 4.81, 95%CI 2.56-9.41), atrial fibrillation (OR = 4.46, 95%CI 2.09-9.51), and coronary heart disease (OR = 2.45, 95%CI 1.32-4.54) as independent factors associated with TNs. Depression and anxiety scores positively correlated with HbA1c (P<0.01) and negatively with NT-proBNP (P<0.05). During median follow-up of 21.8 months, 99.5% patients experienced adverse outcomes. Cox regression showed atrial fibrillation (HR = 1.95, 95%CI 1.35-2.80), diabetes (HR = 1.32, 95%CI 1.02-1.70), and prothrombin activity (HR = 1.01, 95%CI 1.00-1.01) as independent risk factors. Depression was associated with shorter median survival (14.0 vs 18.0 months). Conclusion: Thyroid nodules are associated with greater cardiovascular comorbidity burden, depression, and poorer prognosis in HFrEF patients with anemia and HUA. This association highlights the need for comprehensive management that includes cardiovascular risk assessment and psychological evaluation.
