Differences in the radiographic progression in vdH-S. The mean ± standard deviation (solid horizontal lines and bars) and median (interquartile range [35]; dashed horizontal lines and boxed areas) change in total radiographic score/year were 4.1 ± 4.0 and 4.0 (1.1–6.0) in the repair observed group, respectively; they were 9.3 ± 10.0 and 7.0 (3.5–9.9) in the repair not observed group (*P < 0.05). The mean ± standard deviation and median (interquartile range) change in erosion score/year were 1.1 ± 2.2 and 1.0 (0.0–2.3) in the repair observed group, respectively; they were 5.2 ± 7.6 and 2.7 (1.1–6.1) in the repair not observed group (^†P < 0.01). The mean ± standard deviation and median (interquartile range) change in JSN score/year were 3.1 ± 3.0 and 3.9 (1.2–5.0) in the repair observed group, respectively; they were 4.1 ± 4.4 and 3.0 (1.0–5.6) in the repair not observed group (not significant).
