Values in parentheses are 95 per cent c.i.

^*The 50 per cent value is equivalent to the median time to return to the behaviour.

^†A hazard ratio greater than 1·00 shows that return to the behaviour took longer in the endovenous laser ablation (EVLA) arm. UGFS, ultrasound‐guided foam sclerotherapy.
