Preprandial rintSO2 values compared to postprandial values between PMA groups The bars represent the mean and standard error of the mean of individual rintSO2 values before and after enteral feeding for the different PMA groups; PMA < or ≥ 30 weeks (a), PMA < or ≥ 32 weeks (b). The mean rintSO2 is marked with a o within the bars. Statistically significant differences are marked with an asterisk: * < .05
