Additional file 1 of Radiological pattern in ARDS patients: partitioned respiratory mechanics, gas exchange and lung recruitability

Additional file 1: Figure S1. Study design and patient morphological characterization flow chart. Table S1. Characteristics of the study population at 5 cmH2O of PEEP. Continuous data are expressed as mean (SD) or median [interquartile range], while categorical data are expressed as % (number). Student t test or Mann–Whitney rank-sum test and Chi-square or Fisher exact test, were used as appropriate. Table S2. Respiratory mechanics, gas exchange and quantitative radiological characteristics at two levels of airways pressure in patients divided according to the radiological pattern. Two-way repeated measures ANalysis Of VAriance followed by all pairwise multiple comparison procedures (Holm–Šidák method) were used. Table S3. Focal population characteristics at PEEP 5 cmH2O according to the potential recruitment. Continuous data are expressed as mean (SD) or median [interquartile range], while categorical data are expressed as % (number). Student t test or Mann–Whitney rank-sum test and Chi-square or Fisher exact test, were used as appropriate. Table S4. Changes in respiratory mechanics and gas exchange at 2 levels of PEEP in focal group according to the potential recruitment. Continuous data are expressed as mean (SD) or median [interquartile range]. Student t test or Mann–Whitney rank-sum test, were used as appropriate. Table S5. Respiratory mechanics, gas exchange and quantitative radiological characteristics at two levels of airways pressure in FOCAL pattern group divided according to the potential recruitment. Two-way repeated measures ANalysis Of VAriance followed by all pairwise multiple comparison procedures (Holm–Šidák method) were used. Table S6. Quantitative radiological characteristics at PEEP 5 cmH2O and between two levels of airways pressure in the focal group according to the potential recruitment. Continuous data are expressed as mean (SD) or median [interquartile range]. Student t test or Mann–Whitney rank-sum test, were used as appropriate. Table S7. Diffuse population characteristics at PEEP 5 cmH2O according to the potential recruitment. Continuous data are expressed as mean (SD) or median [interquartile range], while categorical data are expressed as % (number). Student t test or Mann–Whitney rank-sum test and Chi-square or Fisher exact test, were used as appropriate. Table S8. Changes in respiratory mechanics and gas exchange at 2 levels of PEEP in diffuse group according to the potential recruitment. Table S9. Respiratory mechanics, gas exchange and quantitative radiological characteristics at two levels of airways pressure in DIFFUSE pattern group divided according to the potential recruitment. Two-way repeated measures ANalysis Of VAriance followed by all pairwise multiple comparison procedures (Holm–Šidák method) have been used for analysis. Table S10. Quantitative radiological characteristics at PEEP 5 cmH2O and between two levels of airways pressure in the diffuse group according to the potential recruitment. Continuous data are expressed as mean (SD) or median [interquartile range], while categorical data are expressed as % (number). Student t test or Mann–Whitney rank-sum test and Chi-square or Fisher exact test, were used as appropriate.
