Figure 2

Mean penetration aspiration score, in subgroups: Age (≤70, >70), sex (female, male), stroke syndrome (non-TACS, TACS), stroke severity (NIHSS ≤10, >10), stroke type (IS, ICH); DSRS (≤7, >7), mean PAS (≤4, >4), number PAS >3 (0, >0), trial (1, 2, and 3), treatment current (<10, 10–20, and >20 mA), sensitivity current (<8, 8–12, and >12 mA), treatment-sensitivity current (<3.5, ≥3.5 mA). Interaction tests adjusted for trial, age, and baseline NIHSS and PAS.
