Raw population values of CSF ET-1 concentrations (pg/ml) over the first 14 days from the time of insult from 106 aSAH patients (a). Raw data are denoted as samples from high (Inline graphic) and low (open circle) groups as identified by trajectory analysis (a). Log ET-1 concentrations versus time from insult (days) in high (filled circle) and low (filled diamond) groups as identified by trajectory analysis (b). Data are presented as mean log ET-1 values measured per day. The model shows two groups of patients with significantly different (P < 0.001) ET-1 values. Patients in low group (n = 59, 56%) have relatively low ET-1 values (mean at day 1 = 0.31 pg/ml; SE = 0.04; mean at day 14 = 0.41 pg/ml; SE = 0.15) and those in high group (n = 47, 44%) have higher ET-1 values (mean at day 1 = 0.65 pg/ml; SE = 0.08; mean at day 14 = 0.61 pg/ml; SE = 0.06)
