Peripheral vasoconstriction influences thenar oxygen saturation as measured by near-infrared spectroscopy.

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
purposeNear-infrared spectroscopy has been used as a noninvasive monitoring tool for tissue oxygen saturation (StO(2)) in acutely ill patients. This study aimed to investigate whether local vasoconstriction induced by body surface cooling significantly influences thenar StO(2) as measured by InSpectra model 650.
methodsEight healthy individuals (age 26 ± 6 years) participated in the study. Using a cooling blanket, we aimed to cool the entire body surface to induce vasoconstriction in the skin without any changes in central temperature. Thenar StO(2) was noninvasively measured during a 3-min vascular occlusion test using InSpectra model 650 with a 15-mm probe. Measurements were analyzed for resting StO(2) values, rate of StO(2) desaturation (RdecStO(2), %/min), and rate of StO(2) recovery (RincStO(2), %/s) before, during, and after skin cooling. Measurements also included heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), stroke volume (SV), capillary refill time (CRT), forearm-to-fingertip skin-temperature gradient (Tskin-diff), perfusion index (PI), and tissue hemoglobin index (THI).
resultsIn all subjects MAP, CO, SV, and core temperature did not change during the procedure. Skin cooling resulted in a significant decrease in StO(2) from 82% (80-87) to 72% (70-77) (P < 0.05) and in RincStO(2) from 3.0%/s (2.8-3.3) to 1.7%/s (1.1-2.0) (P < 0.05). Similar changes in CRT, Tskin-diff, and PI were also observed: from 2.5 s (2.0-3.0) to 8.5 s (7.2-11.0) (P < 0.05), from 1.0°C (-1.6-1.8) to 3.1°C (1.8-4.3) (P < 0.05), and from 10.0% (9.1-11.7) to 2.5% (2.0-3.8), respectively. The THI values did not change significantly.
conclusionPeripheral vasoconstriction due to body surface cooling could significantly influence noninvasive measurements of thenar StO(2) using InSpectra model 650 with 15-mm probe spacing.
