Variables	Group with agrammatic aphasia, M (SD)	Control group, M (SD)	Stats
Utterance level
Proportion of sentences produced	80.02% (5.86)	98.22% (2.20)	U = 0.00; p = .00*
Proportion of sentences with correct syntax and semantics	44.61% (17.72)	97.21% (3.25)	U = 0.00; p = .00*
Proportion of sentences with flawed syntax	49.73% (17.76)	2.18% (3.29)	U = 0.00; p = .00*
Proportion of sentences with flawed semantics	11.90% (8.47)	.38% (0.89)	U = 7; p = .00*
Sentence level
Sentence complexity ratio	0.24 (0.11)	0.82 (0.26)	U = 0.00; p = .00*
Number of embedded clauses per sentence	0.19 (0.09)	0.71 (0.20)	U = 0.00; p = .00*
