Question special

In Table 2, there were 14 deaths after the 28-day mark, ten in the conservative oxygen, and four in the liberal oxygen group. Can I assume that the ICU deaths correlate with the deaths prior to the 28-day mark, except for a possible two deaths after the 28-day mark in the conservative oxygen group? The five deaths from mesenteric ischemia all occurred by day 13, which are included in the deaths prior to the 28-day mark. What information can you provide about the causes of death after the 28-day mark? Thank you for the information and answers you have provided thus far.
