What the research actually shows
Fifty-one participants were randomized and nine dropped out or were excluded, leaving 42 analyzed. ① Defects: completer analysis, at least 15% attrition, fewer than 200 participants, under 12 weeks, and active control only. ② Each is on the specified list. ③ The report states 51 randomized, nine excluded or withdrawn, 42 analyzed, eight weeks, and wrist-splint control. ④ Larger, longer, all-randomized analysis and an attention or wait-list arm were feasible. One blinded physician performed assessments. Independent funding was not established from a Funding section in the article.
Why this is classified as C (50)
A 1998 eight-week patient-centered RCT randomized 51 and analyzed 42 completers, produced only partly positive results, and lacks confirmatory replication, giving C, 50.
Counterpoint. Nerve conduction and several symptoms did not improve.

The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.

|---|---|---|
| Improved grip strength | B | Positive in one small trial. |
| Reduced pain | B | Positive in one small trial. |
