SD standard deviation, n number of responds on 30-day survey, TE ± A tonsillectomy with or without adenoidectomy, TT ± A tonsillotomy with or without adenoidectomy
aCold dissection technique: cold steel. Hot dissection technique: radiofrequency, bipolar diathermy scissors, bipolar diathermy, ultracision and multiple techniques where one or more techniques were hot. Missing value n = 815
bCold haemostasis technique: none, infiltration with epinephrine, ties, suture ligature. Hot haemostasis technique: unipolar diathermy, bipolar diathermy, radiofrequency and multiple techniques where one or more techniques were hot. Missing value n = 2560. TT ± A indication infection group (n = 212) is only presented in total and not in a separate group
