Summary of ordinary linear regression of the data given in Fig. 5

Cadaver	Slope (N/mm)		Mean force (N) estimated from linear regression
			At 20 mm transport distance		At 40 mm transport distance
	60 mm	40 mm	60 mm	40 mm	60 mm	40 mm
1	0.73	0.35	57.9	51.5	73.4	58.5
2	0.68	0.43	48.9	45.0	62.5	53.4
3	0.88	0.39	47.6	43.5	65.2	51.4
4	1.01	0.89	62.3	54.9	83.2	72.8

For each cadaver, the slope of the regression line and the estimated value at 20 and 40 mm transport distance are given. The estimated slope and the mean force required at 20 and 40 mm transport distance were larger in 60 than in 40 mm bone fragments
