There were 60 patients with baseline FLC below 152 mg/L and 59 with baseline FLC at or above 152 mg/L. FLC indicates involved immunoglobulin free light chain.
Other includes 15 patients microvascular (claudication); 17 patients gastrointestinal; 3 patients pulmonary; 2 patients myopathy; and 1 patient factor X deficiency with splenic rupture. Total does not add up to 35 because patients had more than one type of involvement
