Primary and secondary independent variables were normally distributed. Subjects were divided into low, medium, and high anxiety groups. The primary independent variable was subjective anxiety rated using VAS (0–10), where low anxiety=0–3, medium anxiety=4–6, and high anxiety=7–10. Secondary independent variables were STAI-s (see text) where low anxiety <40, medium anxiety 40–55, and high anxiety <55; and salivary amylase (log10) where low anxiety <3, medium anxiety 3–4, and high anxiety <4.

The use of vasopressors (either ephedrine or phenylephrine) in low, medium, and high anxiety groups (based on VAS), after the administration of spinal anaesthesia. See text for protocol for vasopressor use. Although there appeared to be a trend to increased vasopressor use with increasing anxiety, this was not significant (χ2 test P=0.24; for ordinal series Spearman’s correlation P=0.093).
