Multivariate analyses were done separately for IGVH or ZAP-70 and L/A ratio due to the high concordance between the latter 2 parameters and the former.

*

P for trend test.

ZAP-70 was not independently associated with disease progression or CLL-related death and was then eliminated in the final Cox model.
