RAMA-C	70.97	79.17	0.430	0.570 (0.165, 1.480)	0.575 (0.260, 1.200)	0.916
RAMA-D	90.32	87.50	1.000	0.890 (0.300, 1.505)	0.875 (0.415, 1.505)	0.511

^aPercentage of positive sera defined as those that gave OD values greater than the cutoff OD.

^bAntibody levels are presented as median OD values (lower quartile, upper quartile).

^cAntibody prevalences of protected and susceptible groups were compared using Fisher's exact test.

^dAntibody levels of protected and susceptible groups were compared using the Mann-Whitney test.
