Comparison of eye movement performance from TS patients and Controls in all the tasks

Task	Variable	Controls (29)	TS-overall (39)	P value
Prosaccade	Latency (ms)	274.8±5.3	269.7±4.6	0.12
Prosaccade	Error rate (%)	0.22±0.19	0.66±0.16	0.09⁺

Antisaccade	Latency (ms)	410.4±10.9	415.4±9.4	0.03^*
Antisaccade	Error rate (%)	17.6±2.4	23.2±2.1	0.77

0-back	Latency (ms)	338.3±9.7	335.3±8.2	0.50
0-back	Error rate (%)	3.3±1.0	5.7±0.8	<0.0001

1-back	Latency (ms)	353.4±13.8	370.3±12.0	0.03^*
1-back	Error rate (%)	20.6±2.3	22.5±1.9	0.045^*

Working Memory Load (1-back – 0-back)	Latency (ms)	15.0±12.1	35.0±10.6	<0.001^*
Working Memory Load (1-back – 0-back)	Error rate (%)	17.3±2.0	16.8±1.7	0.25

Format for all values: mean+standard error. P values are from planned comparisons from mixed effect models for latency and Poisson regression models for error rate;
