The extent of a focal tendon abnormality was intrasubstance in none (0%) of 16 patients with full-thickness tears, one (20%) of five patients with bursal surface partial-thickness tears, two (20%) of 10 patients with articular surface partial-thickness tears, and two (15%) of 13 patients with tendons without tear.
1 Adequate Intake (AI), where no RDA has been established, but the amount established is somewhat less firmly believed to be adequate for everyone in the demographic group.  Tolerable upper intake levels (UL), to caution against excessive intake of nutrients (like vitamin A) that can be harmful in large amounts.
For each nutrient, an Estimated Average Requirement (EAR) was set from which an RDI could be derived. (Note that the US:Canadian terminology is 'Recommended Dietary Allowance', or 'RDA'). Whilst the various NRVs are expressed on a per day basis, they should apply to intakes assessed over a period of about 3 to 4 days.
