Table 1. Categories of calibration variables.

Categories of calibration questions for biological hazards
Food supply
E.g. Among all WHO sub-regions, in 2010 what was the proportion of regional vegetable supply (tonnes) that was imported rather than produced domestically in the WHO sub-region with the highest such percentage?
Under 5 years mortality rate
E.g. Based on WHO’s estimates, think of the country in the WHO African Region that had the largest percentage point decrease from 2000 to 2010 in all-cause under-5 mortality that was due to diarrhea. What was that percentage point decrease?
Improved water and sanitation
Disease surveillance
E.g. What will be the rate per 100,000 population of laboratory confirmed human cases of campylobacteriosis in 2012 in all EU member states as reported in EFSA’s annual report?
Categories of calibration questions for chemical hazards
Lead
What did the UNEP Final Review of Scientific Information on Lead report in 2010 as the mean blood lead level for children in Nigeria? Please express your answer as positive micrograms per deciliter (μg/dL)
Cadmium
Inorganic arsenic
Dietary patterns and food supply
E.g. Based on this FAO Food Balance Sheet data, in 2009 what was the mean percentage of rice in the national food supply available for human consumption for countries in the WHO South East Asia Region?
