1 · What the graph read from it

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.

2 · The registry

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

backgroundCongestive heart failure (CHF) has been linked to dementia but for reasons not well understood. Our retrospective cohort study aims to determine if specific measures of CHF severity are associated with cognitive performance or cerebral blood flow velocity (CBFV) among decompensated CHF outpatients. MATERIALS AND

methodsOne hundred and thirty-eight patients with transthoracic echocardiogram ≤1-year preceding consent were included. Forty-nine patients had concurrent transcranial Doppler ultrasonography administered by a trained technician assessing anterior cerebral artery, middle cerebral artery, and internal carotid artery (ICA) CBFV. CHF characteristics considered were NYHA classification, CHF type (heart failure with preserved ejection fraction vs. heart failure with mildly reduced/reduced ejection fraction), and left ventricular ejection fraction (LVEF; continuous [per 5%] or categorized [≤40%, 40%-55%, and ≥55%]). A trained psychometrist administered a standardized cognitive battery including Rey Auditory Verbal Learning Test, Rey Complex Figure Copy and Immediate Recall test, Letter-Number Sequencing (LNS) test, and Trail Making Tests. Adjusted multivariable linear regression models determined the association between CHF characteristics and standardized cognitive tests as well as between CHF characteristics and standardized CBFV, in distinct models.

resultsOn average, NYHA Class 1-2 patients had better LNS scores than NYHA Class 3-4 patients (β: 0.47; 95% CI: 0.09, 0.84). Patients with LVEF 40%-55% had higher ICA CBFVs than those with LVEF ≤40% (β: 13.7; 95% CI: 1.01, 26.39). No associations between other CHF characteristics and either cognitive performance or CBFV were found.

conclusionBlood flow may be an important mechanism behind CHF-related cognitive decline, but studies with larger sample sizes and a control group without CHF are needed.
