Study population of ages <20 years, Sohar and Liwa provinces, Oman, 2006–2010. Results are also stratified by age category and gender.
*Adjusted for time trend.
†Follow-ups were defined as any repeated patients’ visits within 1 month of two ‘new event’ visits.
‡Age and gender standardised according to census population figures for 2010.
§Including high and intermediate exposure zones, with control zone as the reference.
ARD, acute respiratory diseases CI, confidence interval; RR, risk ratio.
