The effect of SB-PS on subjects’ performance in the Rey-AVLT²⁸ assay following 12 weeks’ administration

Rey-AVLT scores (no of words correctly recalled)	Baseline	12 weeks	P-value*
Immediate recall	4.12 ± 0.34	5.12 ± 0.31	0.007
Total learning	36.23 ± 1.90	39.88 ± 1.82	0.013
Best learning	9.42 ± 0.61	9.77 ± 0.47	0.502
Delayed recall	7.15 ± 0.54	7.81 ± 0.59	0.183
Recognition	11.81 ± 0.46	12.46 ± 0.42	0.156

Notes: Mean scores at baseline and following 12 weeks of SB-PS administration are presented. Values are described as mean ± SE; n = 26.

^*Based on Student’s t-test comparison for dependent samples of the mean change between baseline and 12 weeks. Numbers in bold mark significant change from baseline.
