a IL2; b IL4; c IL5; d IL23. Data are expressed as mean ± SEM as relative measures of assay signal (fluorescence intensity); n = 16. The four participants who showed the highest increases in whole blood NAD+ concentration (numbers 11, 17, 23, 26; Fig. 3 and Supplementary Table 1), as well as the late responder (number 18), were included in all *P < 0.05 by Student’s paired t-test.
