Table 1. GRP78 expression levels in bone marrow increased from MGUS to NDMM and RRMM.

Patients	GRP78 levels
	median	[95% CI]	IQR	p-value
MGUS (n = 29)	2.5 ng/mL	1.7–6.4	1.6–8.4
NDMM pts (n = 29)	3.1 ng/mL	1.8–7.3	1.7–11.4
RRMM pts. (n = 15)	4.0 ng/mL	1.6–7.8	1.6–7.3
All pts (73)	3.3 ng/mL	2.0–5.4	1.6–8.4	p = 0.8

Abbrevations: MGUS, monoclonal gammopathy undetermined significance; MM, multiple myeloma; NDMM, newly diagnosed multiple myeloma; RRMM, relapsed refractory multiple myeloma; [95% CI], Confidence interval; IQR, Interquartile range.
