Table 2:
Variables potentially associated with missing LVO at initial CTA evaluation; results of univariate logistic regression analysisa
| Variables | Odds Ratio (95% CI) | P Value |
|---|---|---|
| Interpreter | ||
| Non-neuroradiologists (n = 33) vs neuroradiologists (n = 27) | 7.14 (1.43–35.57) | .02 |
| Senior residents (n = 24) vs neuroradiologists (n = 27) | 1.79 (0.27–11.71) | .55 |
| Senior residents (n = 24) vs non-neuroradiologists (n = 33) | 0.25 (0.06–1.02) | .05 |
| Time of CTA interpretation, on-call hours (n = 40) vs office hours (n = 44) | 1.89 (0.63–5.70) | .26 |
| Reporting of lateralizing symptoms/signs or suspected location of stroke on the request form for CTA; yes (n = 58) vs no (n = 26) | 0.91 (0.29–2.92) | .88 |
| Location of LVO; M2 segment (n = 40) vs distal internal carotid artery and/or M1 segment (n = 42) | 6.77 (1.79–25.57) | .005 |
