Abstract
Policosanols (PC) are very long chain aliphatic alcohols derived from the wax constituent of plants. In the early 1990s, researchers at Dalmer Laboratories in La Habana Cuba isolated and produced the first PC supplement from sugarcane wax. The original PC supplement has been approved as a cholesterol-lowering drug in over 25 countries throughout the Caribbean and South America. Cuban studies claim that 1 to 20 mg/day of the original PC supplement are effective at producing significant reductions in total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C). These studies also show that PC supplements are potent antioxidants, promote proper arterial endothelial cell function, inhibit platelet aggregation and thrombosis, and serve as effective treatments for intermittent claudication. However, for the most part, those studies reporting therapeutic efficacy of PC were carried out by one research group situated in Cuba. Conversely, research groups outside of Cuba have failed to validate the cholesterol-lowering and antioxidant efficacy of PC. Cuban researchers, however, continue to claim that the efficacy is attributed to the unique purity and composition of the original PC preparation, a mixture not found in PC products used by external research groups. The absence of independent and external studies confirming the therapeutic benefits of PC in disease prevention and treatment raises questions regarding their true efficacy.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
