2. Fig 1
The relative reductions of pre-post VAS scores (%, ΔVAS) of patients after intra-articular SIJ injection of short- and long-acting anesthetics. Data are rearranged to separate nonresponders (left side) and responders (right side). Dashed line represents 50% level of the VAS reduction.

3. Fig 2
The ROC curve of the positive pain provocation tests with positive SIJ blocks (≥50% VAS reduction). The number of positive provocation tests (1–5) is shown at the relevant cutoff points of the curve. NOTE. AUC=.799; standard error, .059; 95% CI, .676–.891.
