Table 2.
Baseline characteristics and overall MBW outcomes (from acceptable testing cycles without sighs) of the infants included in this study. For baseline characteristics, we show simple summary statistics: the count for sex and the sample mean and standard deviation for the other variables. For the outcome measurements, we show the fitted mean and standard deviation for the ‘none’ scenario (representing tests without sighs)
| Characteristic (at time of testing) | Observed distribution |
|---|---|
| Sex | 123 male, 123 female |
| Weight (kg) | 4.7 (0.7) |
| Height (cm) | 56 (2.6) |
| BMI (kg/m2) | 15 (1.7) |
| Age (days) | 43 (12) |
| Outcome measurement | Fitted distribution |
|---|---|
| LCI | 6.8 (0.44) |
| CEV (L) | 0.68 (0.046) |
| FRC (L) | 0.088 (0.0072) |
| MR1 | 1.99 (0.12) |
| MR2 | 7.2 (0.89) |
This choice of summary was motivated by the unbalanced replication structure of the data. A ‘simpler’ summary of the outcome measurements is only available at the expense of excluding much of the data (to get a smaller data set without replicates).
