1

Sample size is 5 participants; significance values of any results not reported in the paper.

2

paper reports only significance (P value) without reporting the value of NK cell activity.

3

study I (parallel group study design) reports only significance (P value) without reporting the value of NK cell activity, and study II (crossover design) has less than optimal washout period, and there is a difference in numbers between text and table.

4

paper reports only significance (P value) without reporting the value of T lymphocytes, B lymphocytes, NK cells, and cytokines.

5

paper reports only significance (P value) without reporting the value of T lymphocytes and NK cells.

6

paper reports only significance (P value) and mean difference without reporting the value of immunoglobulins and total or differential white blood cell counts.

NA: Not available; NK: Natural killer; WBC: White blood cell.
