Control: n = 310; No surgery: n = 64, n = 31¹; Ileocecal resection: n = 41, n = 16¹; Colectomy: n = 22, n = 8¹; Other surgery: n = 12, n = 4¹; Ileocecal resection + other surgery: n = 12, n = 9¹. Data expressed as medians.

P < 0.05 vs control,

P < 0.05 vs no surgery,

P < 0.05 vs ileocecal resection,

P < 0.05 vs colectomy (Mann-Whitney U test).
