Data are presented as mean±sd, unless otherwise stated. Values are 2log PC20 values. Between-group differences were tested with t-test. The 23 subjects at the right part of the table are those subjects who reach a PC20 <640 mg·mL−1 with the the small- and large-particle AMP protocol at baseline. DD: doubling dose. # p = 0.17 within group; ¶: p = 0.03 within group.
