As such, total number of advisories issued for each population = 9 For the GP: Number of unrestricted advisories (i.e., 8 meals/month): or % (i.e., out of 9) Number of partially restricted advisories (i.e.,, or meals/month): 5 or 56% (i.e., 5 out of 9) Number of completely restricted advisories (i.e., meal/month or do not eat ): or % (i.e., out of 9) Total number of restricted advisories (i.e., partial + complete): 5 (i.e., 5+=5) or 56% (i.e., 5 out of 9) For the SP: Number of unrestricted advisories (i.e., 8 meals/month): or % (i.e., out of 9) Number of partially restricted advisories (i.e.,, or meals/month): or % (i.e., out of 9) Number of completely restricted advisories (i.e., meal/month or do not eat ): or % (i.e., out of 9) Total number of restricted advisories (i.e., partial + complete): 5 (i.e., +=5) or 56% (i.e., 5 out of 9) 5
