  1. Proteins with increased abundance in pterygium in comparison with controls are shown
  2. FDR: false discovery rate. FEWR: family-wise error rate (Holm-Sidak method). Y: yes, still significant after multiple comparisons correction. N: no, not significant after multiple comparisons correction. § Ubiquitin cluster (UBC; UBB; RPS27A; UBA52). SE: standard error
