Figure 2. VISA-A Scores at Baseline and 6 Months for Each Participant by Group.

Figure 2.

The baseline Victorian Institute of Sport Assessment-Achilles (VISA-A) scores for individual participants are connected using blue lines for the platelet-rich plasma (PRP) group and orange lines for the sham (subcutaneous dry needle injection) group. Changes from baseline (indicated by the pre label) to 6 months (post label) are represented by the vertical lines with upward lines indicating improvement of Achilles tendinopathy and downward lines indicating deterioration. Box plots show the summary of baseline, 6 months, and changes by group. Boxes from bottom to top show the 25th, 50th, and 75th percentiles; horizontal dashed lines indicate the mean; horizontal solid lines indicate the median; whiskers with caps indicate the range from the lower to upper adjacent values (25th percentile−1.5 × the interquartile range [IQR]; 75th percentile + 1.5 × the IQR).
