Variable 1 | Variable 2 | Estimated Spearman Correlation Coefficient | 95% CI | P Value |
---|---|---|---|---|
Right MC volume | CSF opening pressure | −0.104 | −0.323−0.127 | .38 |
Left MC volume | CSF opening pressure | −0.050 | −0.274−0.179 | .67 |
↵a The Spearman correlation coefficient was only −0.10 for right MC volume and CSF pressure, and −0.05 for left MC volume and CSF opening pressure. Correlation coefficients are very close to zero. We may conclude that opening CSF pressure is not correlated with right or left MC volumes.
