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

Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes were compared with 16 age-matched sedentary male controls. Resting-state functional magnetic resonance imaging was used to obtain brain global blood oxygen level-dependent (gBOLD) and CSF inflow signals. The gBOLD-CSF coupling was estimated using cross-correlation function and transfer function analyses in time and frequency domains, respectively. The magnitude of gBOLD and CSF oscillations was also quantified by power spectral density. The cross-correlation-derived gBOLD-CSF coupling was similar between athletes and sedentary controls (-0.30 ± 0.26 vs. -0.33 ± 0.22, P = 0.753). Power spectral density of the CSF inflow signal was significantly greater in athletes (2.83 [2.19, 3.47] z
