A Differences in severity stratification between PALICC and Berlin definition. Most of the 61 subjects meeting PALICC criteria for mild PARDS did not meet Berlin/AECC criteria, 6 also met criteria of mild ARDS by Berlin and ALI byAECC and 6 met criteria of moderate ARDS by Berlin and ARDS by AECC. Of the 45 subjects meeting PALICC criteria for moderate PARDS by PALICC only 6 subject met criteria for moderate ARDS by Berlin and 4 subjects met criteria for severe ARDS by the Berlin definition. Of the 29 subjects meeting PALICC criteria for severe PARDS 8 also met criteria for severe ARDS by the Berlin definition and 3 met Berlin criteria for moderate ARDS. B Reasons PALICC PARDS subjects are not identified as ARDS by Berlin/AECC. 49 subjects with mild PARDS by PALICC were not identified by Berlin/AECC, mainly due to lack of bilateral consolidations (dark blue). For the 35 subjects that were not identified by Berlin/AECC with moderate PARDS and the 18 subjects with severe PARDS a same pattern was seen
