| Met catheter size criteria | 495 (82.5) | 33 (94.3) | 11.8 (–1.4 to 17.0)b |
| Met catheter placement location criteria | 394 (65.7) | 27 (77.1) | 11.5 (–5.1 to 23.0)b |
| Met catheter ultrasound confirmation criteria | 294 (49.0) | 22 (62.9) | 13.9 (–3.1 to 28.4)b |
| Infusion duration, h | 5.5 (1.9-18.9) | 13.8 (4.0 to 29.5) | 6.8 (–3.1 to 19.3)a |
| Infusion duration > 24 h | 116 (19.3) | 11 (31.4) | 12.1 (–1.2 to 28.9)b |
| Maximum dose | 10 (5-15) | 13 (7-15) | 0.6 (–2.1 to 3.8)a |
Data are presented as No. (%) or median (interquartile range), unless otherwise indicated. Effect estimates with 95% CIs compare the effect in the group of patients experiencing extravasation with the effect in the group of patients not experiencing extravasation.
a
Mean difference.
b
Absolute percentage difference.
