Fig 6. Summary of frequency of responding donors and magnitude of response of all cytokines in all donors.

(A) the graph shows the frequency of responding donors to all cytokines (eg one positive hit for one cytokine equals a positive donor) and (B) the graph the corresponding magnitude of the response expressed as an average of spot forming cells (SPC) for all cytokines. n = 22. The difference in frequency was calculated using a one-sided Fisher’s test.
