Supplementary Figure 1 . Flowchart of groups included in this study. A retrospective sample of 120 participants was further classified into two mutually exclusive groups for use in the VLSM study: CS task group, which included participants with a connected speech assessment, and PNT task group, which included participants with a naming assessment. The PNT task group was matched, using case-control matching, on the aphasia severity of the CS task group. To directly evaluate behavioral distribution of paraphasias, we evaluated a subgroup of the CS task group, which we have called the CS+PNT subgroup because members of this group had both a connected speech and naming assessment. Notably, members of this group were not included in the PNT task group, as we created the CS and PNT task groups (for VLSM analysis) to be mutually exclusive. .
