The impact of posture changes on critical closing pressure and resistance-area product regulation in healthy subjects.

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
introductionCerebral blood flow (CBF) is affected by posture changes, but there is a paucity of research examining the effect of posture on dynamic cerebral autoregulation (dCA). The step responses of critical closing pressure (CrCP) and resistance area product (RAP) obtained from the cerebral blood velocity (CBv) signal can reflect the changes in dCA, enabling exploration of dCA changes in supine, sitting and upright postures.
methodsIn 22 participants (11 males, aged 30.2 ± 14.3 years), two recordings were made for each posture, corresponding to supine, sitting, and standing. Blood pressure (BP, Finometer), MCAv and PCAv (transcranial Doppler ultrasound), end-tidal carbon dioxide (EtCO
resultsMoving from supine to sitting, and then standing, led to reductions in mean MCAv (p < 0.001), PCAv (p = 0.037), BP (p < 0.001) and EtCO
conclusionPosture changes can significantly affect the step responses of MCAv, CrCP, and RAP. The interaction between posture and EtCO
