Pain scores at baseline and at 30, 60, and 120 minutes
Time of pain assessment (minutes)
Pain scores measured after an emergency physician-performed ultrasound-guided nerve block in emergency department patients with a proximal femoral fracture. 0, absolutely no pain; 10, most extreme pain. Boxes show median and interquartile range, whiskers mark the minimum and maximum (1.5 × lower and upper quartile), dots are outliers. NRS, numeric rating scale. * p < .001, ** p < .001, *** p = .03.
