From: Can pre-operative intraarticular injection predict pain relief after total hip arthroplasty?
Pain at different time points (n = 88). This boxplot shows the pain assessment using a numeric rating scale at different time points (baseline (pre-injection), after 15 min (diagnostic phase) and at first clinical follow (after around 2 months) (therapeutic phase) (post-injection), and at last follow up (after around months) (post-operatively after primary total hip arthroplasty)
