Table 5.

The association between percentage weight loss and cumulative nutritional impact symptoms (NIS) and cumulative NIS interfering with oral intake at each follow-up. β is the — slope in association, as estimated from marginal trends derived from a mixed model for repeated measures. The value of β represents the expected change in percentage weight loss when increasing one point on the total NIS scale (range 17 to 85)
