Sedation-free success rates in different subgroups of patients.

Subgroup	No. of patients in subgroup	No. successful sedation-free reductions	Success rate
Overall	106	87	82%
Male patients	78	65	83%
Female patients	28	22	79%
Without greater tuberosity fracture	84	72	86%*
With greater tuberosity fracture	22	15	68%
Patients with BMI<25 kg/m2	62	53	85%
Patients with BMI>25 kg/m2	40	30	75%
Primary dislocation	92	74	80%
Repeated dislocation	14	13	93%**
Age <30 years	27	24	89%
Age >60 years	35	28	80%
Male patients with repeated dislocation	10	10	100%

*significant difference (p < 0.01) compared to patients with greater tuberosity fracture;

**significant difference (p < 0.01) compared to patients with primary dislocation; data for BMI calculation was available for 102 patients. Level of significance was adjusted with a Bonferroni correction for 5 subgroups (0.05 / 5 = 0.01).
