Table 3. Distributions of all patients, stratified according to gender and arm to which they were assigned at randomization (top).

Characteristic		Minimum	25%	50%	75%	Maximum
Age (years)
Male
Control	N = 27/27	55.4	62.4	68.5	74.2	86.5
Metastasectomy	N = 31/31	35.3	58.5	66.4	72.1	82.8
Female
Control	N = 20/20	48.2	54.3	61.3	74.3	83.2
Metastasectomy†	N = 14/15	50.8	64.4	71.6	64.4	76.5
CRC resection interval (months)
Control‡	N = 46/47	2.0	17.2	27.4	35.0	130.5
Metastasectomy§	N = 45/46	1.0	13.8	23.1	36.8	106.5
Number of metastases
Control¶	N = 46/47	1	1	2	3	8
Metastasectomy	N = 46/46	1	1	2	3	6

Values are given as minimum, maximum and quantiles. The quantile distribution of the number of metastases is as follows: for 1, 2, 3, 4 and 5 metastases the exact numbers for control patients were 16, 16, 7, 3 and 3, and for metastasectomy patients they were 16, 17, 8, 2 and 1, with one patient in each arm having more than 5 metastases – 8 and 6, respectively.

^†We know from minimization data that the age category of the missing patient was 61+ years.

^‡From minimization data, the missing colorectal cancer (CRC) resection interval [i.e., the time elapsed between the primary CRC resection and the metastasectomy operation] was 1–3 years.

^§The missing CRC resection interval was <1 year.

^¶From minimization data, the metastasis count was >5.
