Predicting the macrovascular contribution to resting-state fMRI functional connectivity at 3 Tesla: A model-informed approach.

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
Macrovascular biases have been a long-standing challenge for functional magneticresonance imaging (fMRI), limiting its ability to detect spatially specificneural activity. Recent experimental studies, including our own, foundsubstantial resting-state macrovascular blood-oxygenation level-dependent (BOLD)fMRI contributions from large veins and arteries, extending into theperivascular tissue at 3 T and 7 T. The objective of this study is todemonstrate the feasibility of predicting, using a biophysical model, theexperimental resting-state BOLD fluctuation amplitude (RSFA) and associatedfunctional connectivity (FC) values at 3 Tesla. We investigated the feasibilityof both 2D and 3D infinite-cylinder Models as well as macrovascular anatomicalnetworks (macro-VANs) derived from angiograms. Our results demonstrate that (1)with the availability of macro-VANs, it is feasible to model macrovascular BOLDFC using both the macro-VAN-based model and 3D infinite-cylinder Models, thoughthe former performed better; (2) biophysical modelling can accurately predictthe BOLD pair-wise correlation near to large veins (with R
