Table 3. Summary of multivariate logistic regression analyses of risk factors for clinical and radiological pneumonia.

	Neutrophils >7.5×109/L & CRP ≥40mg/L
Very Severe Pneumonia
Odds Ratio (95% CI)	1.66 (0.85–3.24)
p-value	0.09
Primary Endpoint Pneumonia
Odds Ratio (95% CI)	2.37 (1.56–3.59)
p-value	<0.001
Other Infiltrate
Odds Ratio (95% CI)	0.54 (0.36–0.81)
p-value	0.003

Episodes of pneumonia categorised clinically as very severe pneumonia, radiologically as primary endpoint pneumonia or other infiltrate were compared to all other pneumonia episodes.
