Prospective paired crossover evaluation of potential impact of investigator gender on perceived pain intensity early after acute or scheduled surgery

Table 2 Differences in pain intensity levels in relation to pain intensity intervals

Average pain intensity (VAS units)	Number of patients	Median (IQR) difference in pain intensity between evaluations by males and females (VAS units)
≤ 1.4	68	0.1 (− 0.2, 0.6)
1.5–2.4	46	0.1 (− 0.4, 0.6)
2.5–3.4	52	0.3 (− 0.4, 0.9)
3.5–4.4	41	0.2 (− 0.6, 1.4)
4.5–5.4	21	0.1 (− 0.6, 0.8)
≥ 5.5	16	0.2 (− 0.4, 1.0)
