  1. **Sidak binary comparison test; *p < 0.05, statistically significant
  2. AD autosomal dominant; AR autosomal recessive; X-linked X-related inheritance pattern; ERG amplitude full-field flicker electroretinography, amplitude (mV); ERG implicit time full-field flicker electroretinography, implicit time (ms); T0 (baseline) just before the Wharton jelly-derived mesenchymal stem cell injection; T2 12th month after injection
