Formula for increment in density

Increment in density (ID)
ID 7	RESULT 2 − RESULT 1/25
ID 21	RESULT 3 − RESULT 1/25
ID 42	RESULT 4 − RESULT 1/25

ID 7, 21 and 42 were the increments in density at 7th, 21st and 42nd days, respectively

RESULT 1: the mean radiodensity at the fracture site preoperatively, RESULT 2: the mean radiodensity value at the fracture site on the seventh day postoperatively, RESULT 3: the mean radiodensity value at the fracture site at 21 days, RESULT 4: the mean radiodensity value at the fracture site at 42 days
