Kaplan-Meier plot of survival in people with elevated (>43.3mg/L) versus normal combined serum cFLC concentration.

<p>Participants with combined free light chains (cFLC) ≤43.3 mg/L had significantly longer overall survival compared to participants with cFLC >43.3 mg/L. Log rank analysis: P <0.001. Note that the <i>x</i> axis does not intersect the <i>y</i> axis at zero.
