The differences in style between Buena Vista and Motul probably results from differing epochs of construction.
Since customization and flagging will differ epoch-to-epoch, each epoch has a dedicated.x file, identified by the epoch number (.x.1,.x.2, etc).
Finally, we examined how these relationships differed at different epoch lengths, ranging from 1 to 60 s.
Consider that the corresponding power allocation vectors, PA and PB, also differ at epoch s such that P i A = P i B, ∀ i ∈ { 1, 2,.., s − 1 } and P s A < P s B. First, assume that PA remains constant after epoch s, i.e., P i A = P s A, ∀ i > s.
Search strategies differed somewhat and spanned different epochs, but the conclusions were broadly similar.
Neonatal factors known to affect survival did not differ in epochs 1 and 2 (Table 1).
The association between transfer status and survival did not differ between epochs (P=0.15 from likelihood ratio test comparing models with and without interaction between transfer and survival).
While one concern with desflurane has been airway irritability [ 20], albuterol use did not differ between epochs, suggesting there was not increases of bronchospasm.
We used multivariable logistic regression to examine the association between 28 day survival and transfer, and between transfer and multiple birth, with the inclusion of interaction terms to test whether the association differed between epochs.
Among those who were discharged, length of stay did not differ significantly between Epoch I vs. Epoch II (37 [19, 55] vs. 34 [23, 67] days; rank sum test P = 0.615).
