Group GD: children received granisetron at 40 mcg/kg and dexamethasone at 150 mcg/kg.
Chi-square test.

¥ represents number of children who had complete response (no PONV between 0 and 24 hrs).
£ represents number of children who had nausea at some point of time between 0 and 24 hrs.
¢  represents number of children who had vomiting at some point of time between 0 and 24 hrs.
µ represents number of children who needed antiemetic at some point of time between 0 and 24 hrs.
