- Patients with identified sites of infection (N = 97) were stratified into the following subgroups: non-respiratory (abdominal + urinary + other; N = 48) and respiratory (pneumonia + non-pneumonia; N = 49). Parameters that varied significantly (p < 0.05) between these two groups were identified by statistical testing (t test for continuous parameters; two-proportions z-test for categorical parameters)
- 1Two-tailed t test for all parameters except for overall agreement and number of indeterminates, for which a two-proportion z-test was run instead (www.vassarstats.net)
