| Methods |
Design: three group parallel trial
Purpose: study the analgesic effect of accupressure |
| Participants |
Patients: victims of minor trauma under transport to hospital
Baseline comparability: yes (age, gender) |
| Interventions |
Placebo: stimulation on sites not regarded analgesic acupressure sites
Untreated: no stimulation
Experimental: stimulation on sites regarded analgesic acupressure sites (Di4, KS9, KS6, BL60, LG20)
(Co‐intervention: no) |
| Outcomes |
Pain (100 mm VAS)
Anxiety (100 VAS)
Heart frequency |

| No signs of variance inequality or skewness? |
Low risk |
No variance inequality (F‐test not statistically significant) and no skewness (1.64 standard deviations does not exceed the mean) |
| Trial size > 49? |
High risk |
N = 41 |
| Clearly concealed allocation + trial size > 49 + drop‐out max 15% |
High risk |
Trial size < 49 |
