Table 6. Multiple correlation analyses of [EPO + hemopexin + total heme] with [TNF-α + IL-10 + IP-10 + MCP-1] during MM.

	Estimate	Std. Error	t-value	Pr (>|t|)
(Intercept)	345.1181	60.3095	5.722	1.11e-05
TNF-α	0.5480	0.1463	3.747	0.0012
IL-10	0.0788	0.0641	1.229	0.2326
IP-10	0.0307	0.0164	1.875	0.0748
MCP-1	-0.2493	0.1644	-1.516	0.1444

The estimated coefficient (Estimate) corresponds to the fitted variable value, the standard error (Std. Error) indicates the variability of the estimated coefficient, the t-value measures whether or not the estimated coefficient for this variable is meaningful for the model, and the variable p-value (Pr (>|t|)) indicates the probability that the variable is not relevant in the model. R = 0.33 CI (-0.049–0.626); p-value = 0.1054.
