Data are median (Q1, Q3) all in mg/dL. % change from baseline calculated compared to long term follow-up by paired t-test. NA-indicates data was not available. RYGB and Non-op participants excluded from this table include pregnant participants, those on lipid lowering medication, those with lipids missing or those that were non-fasting.
