Outcome.

Outcome	PCR− Group	PCR+ Group	Difference in Means or Proportion	Pr(Diff > 0) b
	No = 66	No = 198	(CrI) a
In−hospital mortality, n (%)	6 (9.1)	19 (9.6)	0.01 (−0.07;0.09)	0.50
ICU admission, n (%)	15 (22.7)	61 (30.8)	−0.07 (−0.19;0.05)	0.11
Hospital LOS, days, mean (SD)	8.7 (7.4)	9.8 (8.3)	−1.01 (−3.06;1.16)	0.17

^a (CrI) = credibility interval; ^b Pr(diff > 0) = probability that the difference is larger than 0. Data are all expressed in mean (SD) or n/No (%) where No is the total number of patients with available data. Abbreviations: SD = standard deviation; ICU = intensive care unit; LOS = length of stay.
