Minor amputation was positively correlated with procalcitonin and negatively correlated with the ankle-brachial pressure (ABI) and transcutaneous oxygen pressure (TcPO₂), with the correlation strengths of ABI and TcPO₂ > procalcitonin. OR: Odd ratio; ABI: Ankle-brachial pressure; TcPO₂: Transcutaneous oxygen pressure; PCT: Procalcitonin.
