These tests indicated that the change in the REG group, even though larger (+0.64 ng/ml) was not statistically significant ( p = 0.12), while the smaller change in the OFD group (-0.32 ng/ml) was barely significant ( p = 0.049), this result underscores the difference in variance between the 2 groups.
There was a significant trend in CEMP-1 over time, and this trend was different among the 2 groups: the REG group showed a statistically significant rising CEMP-1 trend (0.18 ng/ml a week p = 0.012), while the OFD had a trend that was significantly lower (-0.22 ng/ml a week compared to the REG group trend p = 0.023), the OFD group lost on average 0.05 ng/ml a week.
