#These values show that there is a moderate relationship between SAP. MAP. DAP. HR and NIRS-left in the relevant time periods.
*These values are close to statistical significance. Therefore. it is defined as there is a tendency towards meaningfulness.
¥These values show that there is a high severity relationship between DAP. MAP and NIRS-left in the relevant time periods.
P values marked with dark black are statistically significant. D; desflurane. P; propofol
