From: Stress responses in surgical trainees during simulation-based training courses in laparoscopy
The correlation between participants’ characteristics; gender, age, work exp.= work experience as surgical trainees in months, simulation exp.= laparoscopic simulation experience, main surgeon = experience as main operative surgeon, assisting surgeon = experience as assisting surgeon, gaming exp.= computer game experience, fine motor skills = fine motoric activity, and stress markers; saliva cortisol = cortisol, STAI-6 score = State-Trait Anxiety Inventory scores, SDNN = standard deviation of all R-R intervals, RMSSD = root mean square of successive differences of R-R intervals, LF/HF ratio, ratio of low-frequency (LF) to high-frequency power (HF), and Poincaré = the Poincaré ratio, ratio of SD2 to SD1. Circle sizes and shade correspond to the strength of the correlation values. Red colour denotes positive values and green colour denotes negative values
