Notes: ^aComparison between OM group and NOM metastases group by nonparametric sum up tests. P<0.05 was considered statistically significant.

Abbreviations: OM, ocular metastasis; NOM, non-ocular metastasis; TC, total cholesterol; TG, triglyceride; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
