Results (mean ± standard deviation) from SRμCT analysis of the ex vivo data and the comparison factor between the ex vivo and in vitro analysis – parameters related to the screw (FM = factor mean, which is the ratio between the mean ex vivo value and mean in vitro value; FS = factor standard deviation, which is the ratio between the standard deviation ex vivo value and standard deviation in vitro value).
