Differences between the SLE and HC groups for each of the CANTAB outcome measures

Variable*	Measurement	SLE, n=36	HC, n=30	P value
		Mean (SD), Median (LQ, UQ), n (%)
PAL+ (visual memory and new learning)	Total errors (adjusted)	29.50 (19.00, 79.75)	24 (10.75, 48.75)	P=0.095
VRM (verbal memory)	Free recall – total correct (Max.=18)	10 (8, 13)	10 (8.75, 14)	P=0.327
RVP (attention)	Total hits (Max.=27)	13 (12, 20)	20 (15.75, 22)	P= 0.002
ERT (emotional processing)	Average percentage correct – total (%)	61.49 (8.85)	66.94 (9.36)	P= 0.019
	Overall mean response latency – total (ms)+	1626.10 (1411.71, 2274.22)	1343.15 (1152.27, 1744.23)	P= 0.012
OTS+ (executive function)	Mean choices to correct	1.40 (1.27, 1.73)	1.33 (1.18, 1.62)	P=0.484
SWM+ (working memory)	Between errors	108.41 (57.96)	94.73 (52.36)	P=0.328

Missing data: VRM: 1 SLE, ERT: 1 SLE; RVP: 1 SLE; SWM: 2 SLE; OTS: 1 SLE.

P-values in bold are significant at <0.05.

*Higher scores indicate better performance except where indicated with a “+”.

ERT, emotional recognition task; OTS, one touch stockings; Pal, paired associate learning; RVP, rapid information visual processing; SWM, spatial working memory; VRM, verbal recognition memory.
