  "statement": "In 50 lipedema patients versus 50 controls, ICG lymphography and lymphoscintigraphy revealed slower superficial lymph flow (ICG reached upper calf in 8% vs 56%, p<0.0001), more numerous and dilated/tortuous lymphatic vessels, higher fluorescence intensity, higher skin water concentration in the feet (p=0.000189), and increased subcutaneous tissue stiffness, supporting their utility in diagnosing lipedema.",
