Table I.

A summary of the mean, median, range, standard deviation and standard error of the mean for Young's moduli (E) resulting from Hertzian fits to force-indentation profiles measured for various treatment groups. The number of indentation events is indicated by n.

Treatment group	Mean of E (kPa)±standard error (kPa)	Median of E (kPa)	Standard deviation of mean E (kPa)	Range of E (kPa)	r² for Hertz model
Micromass (n = 338)	1.850±0.005	1.41	1.60	0.177–9.07	0.992
Micromass + TGF-β3 (n = 480)	0.498±0.001	0.392	0.276	0.128–2.22	0.988
Pellet (n = 757)	3.810±0.002	3.60	1.69	0.621–11.9	0.990
Pellet + TGF-β3 (n = 733)	0.871±0.001	0.837	0.400	0.155–2.85	0.994
CBR (n = 1090)	171±0.339	45.8	371	2.17–485	0.965
