IgG titer level above COI threshold: COI ≥ 1.0) in BCL patients on active treatment or within 9 mo after treatment with B-cell–directed therapy vs patients with BCL under observation >9 months after B-cell–directed therapy; vs patients with BCL, TCL, or MM receiving other treatments; vs HCP < 65 y of age; vs nursing home residents > 65 y of age. Data are expressed as the number of patients (percentage of total patients in the study group).
MM, multiple myeloma; TCL, T-cell lymphoma.
Data from KSL Inc.
In comparison with patients with BCL receiving B-cell–directed treatment within 9 mo.
