Figure 6.
Plaque morphology and disease severity. Percentage of capped plaques vs. (a) hospital admission (admitted (n = 104), not admitted (n = 16)), (b) duration of hospitalization (n = 120), (c) requirement for intensive care (ICU (n = 22), non-ICU (n = 98)), and (d) respiratory failure (intubated (n = 16), not intubated (n = 104)). (e) Plaque sharpness vs. duration of hospitalization (not sharp (n = 105), sharp (n = 29)). (f) Plaque sharpness vs. hospital admission (admitted: not sharp (n = 85), sharp (n = 27), not admitted: not sharp (n = 20), sharp (n = 2)), requirement for intensive care (ICU: not sharp (n = 15), sharp (n = 9), non-ICU: not sharp (n = 90), sharp (n = 20)) or respiratory failure (intubated: not sharp (n = 12), sharp (n = 6), not intubated: not sharp (n = 93), sharp (n = 23)). Open bars represent not sharp and black bars represent sharp plaques. The analyses were not statistically significant (P > 0.05). Data contain both RSV-A- and RSV-B-infected patients whose duration of hospitalization, respiratory failure, and ICU admission were evaluated retrospectively upon discharge. The Mann–Whitney U-test was used in panels a and c,e.
