Despite more than 30 years of effort that has been dedicated to the improvement of grading systems for evaluating the quality of research study designs considerable shortcomings continue.
Grade 3-4 seneuropathyoccurredccurred more frequently in solvent-based paclitaxel arm than Abraxane arm (12% vs 3%) and the median time to improvement of Grade 3-4 neuropatoy to Grade 1 is much less for Abraxane arm than solvent-based paclitaxel arm (38 days vs 104 days).
After 3 weeks treatment, 11 horses were unchanged or worse, 12 were graded 0, five graded 1, ten graded 2, five graded 3 and four horses were graded 4. Consequently, an improvement of 1 grade was seen in eight horses, 2 grades in ten horses, 3 grades in three horses and 4 grades in four horses in the ImproWin® group.

Improvement of ⩾3 grades in PGA was experienced by 8142%2%, 13 missing) of the 206 patients with a baseline PGA greater than "mild".
The improvement of 4 grades was seen in four horses after 3 weeks and six horses at the end of treatment in the ImproWin® group.
Comparatively, an improvement of 4 grades was not seen in any of the placebo treated horses after 3 weeks and in only one horse at the end of treatment.
An improvement of 1 grade was seen in five horses, 2 grades in ten horses and 3 grades in three horses.
