Boxplots of histomorphometric measurements of Coll II expressed as percentage in bovine cartilage explants. Black line = median; extreme values = minimum-maximum. Control (CTR), exposed to PEMF (PEMF), treated with IL1β (IL1β) or treated with IL1β and stimulated with PEMF (IL1β + PEMF) explants. 24 h, 7 and 21 days (n = 6). Mann-Whitney U test: - Within each experimental time: IL1β versus CTR (*, p < 0.05; **, p < 0.005); PEMF versus CTR (°, p < 0.05); IL1β + PEMF versus IL1β (§, p < 0.05; §§, p < 0.005); - Within each group: 7 days versus 24 h (a, p < 0.05); 21 days versus 7 days (b, p < 0.005)
