Group Values (mean±SD) for Number of Words and the Three CoVec Variables, among Patients with and without Derailment and Tangentiality

	Number of Words	Mean Similarity	Coherence-5	Coherence-10
Derailment
Patients with moderate to severe derailment, n=28–31	16.23±6.52	0.496±0.063	0.559±0.043	0.480±0.053
Patients without derailment, n=127–129	19.31±5.61	0.507±0.037	0.569±0.030	0.495±0.035
	p=0.009 d=0.51	p=0.200 d=0.23	p=0.100 d=0.27	p=0.060 d=0.33
Tangentiality
Patients with moderate to severe tangentiality, n=54–57	18.67±6.30	0.503±0.050	0.565±0.036	0.487±0.043
Patients without tangentiality, n=89–91	19.00±5.50	0.508±0.030	0.569±0.032	0.493±0.039
	p=0.740 d=0.05	p=0.550 d=0.12	p=0.560 d=0.12	p=0.430 d=0.15

p= significance of between-group comparisons when controlling for number of words

d=Cohen’s d effect size computed using raw data rather than estimated marginal means

Note: The sample size varied among number of words and three CoVec variables since CoVec excluded animal lists with less than five or ten words generated for Coherence-5 and 10, respectively.
