The IV is treatment group for patients with drug-induced shivering (extremity wraps vs high room temp vs normal room temp without wraps) same patient used for each treatment; the DV is myocardial oxygen consumption, measured before and after treatment.
e. The IV is length of gestation (preterm vs term vs postterm); the DV is delivery type (vaginal vs Caesarean)
