↵† No interactions were observed in the models. The Hosmer–Lemeshow goodness-of-fit statistics for the recurrent laryngeal nerve palsy and hypocalcaemia models were 0.93 and 0.52, respectively. The c-statistics for the recurrent laryngeal nerve palsy and hypocalcaemia models were 0.65 (95% CI 0.60 to 0.71) and 0.68 (95% CI 0.64 to 0.72), respectively.
