Investigating Physical Exercise and Cognitive Training Effects on Cognition and Brain Health in Men and Women with Heart Failure: The ReCARDIO Trial.
Article in CJC open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04970888 (Comparing the Effects of Combining Cognitive and Physical Exercise Training on Cognition, and Cerebral Blood Flow Regulation in Men and Women With Chronic Heart Failure), which is not on this 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.

Abstract
Cognitive impairment can affect up to 50% of patients with chronic heart failure (CHF) and is associated with reduced treatment adherence, high mortality rates, and poor quality of life. Nonpharmacologic strategies, including cognitive intervention and physical exercise training, may help enhance cognition in patients with CHF. Recent studies in dementia prevention have shown that combining cognitive and exercise interventions could have synergistic effects on cognition, but scientific evidence for the benefits in CHF patients is lacking. Moreover, how men and women with heart failure may differ in their response to nonpharmacologic interventions is also unknown. This randomized controlled trial will investigate the effects of combining cognitive and exercise training, on cognition and cerebral blood flow regulation in men and women with CHF. To achieve this, 216 participants (50% female) with stable CHF regardless of etiology and left ventricular ejection fraction will be randomized to 1 of the 3 following arms: 1. combined cognitive and exercise training; 2. exercise training alone; 3. usual medical care with standard cardiovascular rehabilitation. The first 2 groups will engage in a 6-month intervention, whereas those in group 3 will take part in a standard 3-month cardiac rehabilitation program. The primary endpoint will be changes in cognitive performance from baseline to 6 months based on 4 cognitive composite scores (global cognitive functioning, memory, executive functions, processing speed). Secondary outcomes will include changes in cerebral blood flow regulation (neurovascular coupling, pulsatility, and autoregulation). Tertiary outcomes will include cardiorespiratory fitness, physical functioning, and quality of life. Clinical Trial Registration: NCT04970888.
