Pain intensity during the conversion from parenteral to oral ketamine. Slight: 1–3/10; moderate: 4–6/10; severe: ≥7/10. The medians and ranges of pain intensity (expressed on a numerical rating scale) and significance levels are in the bottom box. Statistical difference vs. a) “before starting ketamine” and b) “the end of s.c. ketamine” (Friedman-Dunn multiple comparisons test) (n=29 patients).
