Table 2. Interobserver Reliability of Radiographic Measurement.

Radiographic measurement	ICC (95% CI)
AP talo-first MTT angle (°)	0.87 (0.73–0.94)
AP talonavicular coverage angle (°)	0.92 (0.86–0.96)
AP talocalcaneal angle (°)	0.89 (0.79–0.94)
AP talo-fifth MTT angle (°)	0.90 (0.81–0.95)
Lateral talo-first MTT angle (°)	0.89 (0.81–0.94)
Lateral calcaneal pitch angle (°)	0.85 (0.72–0.92)
Lateral calcaneo-fifth MTT angle (°)	0.86 (0.75–0.92)
Lateral talocalcaneal angle (°)	0.91 (0.82–0.95)
Lateral talohorizontal angle (°)	0.92 (0.84–0.96)
Lateral first-fifth MTT angle (°)	0.89 (0.80–0.94)
Lateral naviculo-cuboid overlap (%)	0.81 (0.63–0.89)
Medial-lateral column ratio (%)	0.96 (0.90–0.98)

ICCs and 95% CIs were used to summarize the interobserver reliability of radiographic measurements. They were calculated in the setting using a two-way random effect model assuming a single measurement and absolute agreement.

ICC: intraclass correlation coefficient, CI: confidence interval, AP: anteroposterior, MTT: metatarsal.
