  "statement": "In a comparative lymphoscintigraphy study (15 women with lipedema vs 15 with primary lymphedema), inguinal lymph nodes were absent in 14/15 lymphedema cases but only 1/15 lipedema cases (p<0.001) and colloid half-life was longer in lymphedema (230±92 vs 121±36 min, p<0.01), and the Stemmer sign is positive in lymphedema but negative in lipedema, with the review describing lymphedema and lipedema as distinct entities and lipedema's fat distinct from obesity (weight loss reduces truncal but not limb fat).",
