a Boxplot of forced vital capacity (FVC) for group and time in patients receiving crystalloids (dark boxes) or colloids (light boxes). °Represents outliners, *represents extreme outliners, numbers represent number of patients performing spirometry. No significant difference in the time trend from 6 to 48 h was found between the groups (p = 0.38). Furthermore, the difference in time trend from 6 to 24 h (p = 0.2) did not show a significant result. b Boxplot of forced expiratory volume in 1 second (FEV1) for group and time in patients receiving crystalloids (dark boxes) or colloids (light boxes). °Represents outliners, *represents extreme outliners, numbers represent number of patients performing spirometry. No significant difference in the time trend from 6 to 48 h was found between the groups (p = 0.32). Furthermore, the difference in time trend from 6 to 24 h (p = 0.2) did not show a significant result. c Boxplot of peak expiratory flow (PEF) for group and time in patients receiving crystalloids (dark boxes) or colloids (light boxes). °Represents outliners, *represents extreme outliners, numbers represent number of patients performing spirometry. No significant difference in the time trend from 6 to 48 h was found between the groups (p = 0.12). Furthermore, the difference in time trend from 6 to 24 h (p = 0.193) did not show a significant result
