- Spearman rank correlation analysis of concentrations of estradiol, progesterone and testosterone in serum and CSF with transcranial Doppler velocities demonstrated very weak correlations. An absolute value of the correlation coefficient (rho) of 0.00–0.19 indicates a very weak correlation, 0.20–0.39 a weak correlation, 0.40–0.59 a moderate correlation, 0.60–0.79 a strong correlation and a value of 0.80–1.0 a very strong correlation
- CSF cerebrospinal fluid
