Survival data of 59 patients stratified into 3 risk groups according to baseline CTC counts
Risk Group Death N (%) Censored N (%) Quartile Survival [weeks] Median Survival [weeks]
CTC-L (0 CTC) N = 20 2 (10.0) 18 (90.0) 100 95%CI = [85,+oo] >100 95%CI = [85,+oo]
CTC-M (1-4 CTC) N = 15 7 (46.7) 8 (53.3) 32 95%CI = [12,78] >78 95%CI = [20,+oo]
CTC-H (≥5 CTC) N = 24 17 (70.8) 7 (29.2) 22 95%CI = [2,42] 60 95%CI = [27,73]
TOTAL N = 59 26 (44.1) 33 (55.9) 46 95%CI = [20,70] 100 95%CI = [70,+oo]

Quartile and median survival times are given together with confidence intervals (CI). N is the number of patients in the respective group.
