Serum albumin level did notincrease significantly within groups (P , 0.90 vs. P , 0.82) with no difference between groups (P = 0.39). The increase in CD4 cell count within groups was significant (P , 0.01 in both groups), with a significantly higher CD4 count in the spirulina group compared to subjects on soya beans at the end of the study (P = 0.02)
