Patients with small HTX (pleural fluid volume &lt;400\u00a0mL on admission chest computerized tomography [CT]) were included. Patients were considered as being \u201cinitially observed\u201d if there was no intervention for the HTX within 48\u00a0hours after admission. Primary outcome was any HTX-related intervention (open, thoracoscopic or percutaneous procedures) occurring after 48\u00a0hours and up to 6\u00a0months after injury. Univariable and multivariable statistical analyses were employed. A P-value of &lt;.05 was considered significant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 335 patients with HTX, 188 (59.6%) met inclusion criteria. Median (interquartile range) HTX volume was 90 (36-134)\u00a0ml. One hundred and twenty-seven (68%) were initially observed. Of these, 31 (24%) had the primary outcome. These patients had a larger HTX volume (median, 129 vs 68\u00a0mL, P = .0001), and number of rib fractures (median, 7 vs 4, P = .0002) compared to those without the primary outcome. Chest-related readmission occurred in 8 (6%) with a median of 20\u00a0days from injury. Of these, 7 required an HTX-related intervention. Logistic regression analysis found that both the number of rib fractures and HTX volume independently predicted the primary outcome.<\/jats:p>\n                  <\/jats:sec>\n
