Main Article

Estimates of the net effect of LPM closures by comparing the reductions in the number of influenza A(H7N9) infections between study sites with and without closures, adjusting for similar season pattern of absolute humidity, China*

Study sites with LPM interventions				Reduction in no. infections, % (95% CI)
	Reference sites without LPM interventions			Study sites with LPM interventions, R₁	Reference sites without LPM interventions, R₂	Difference in reduction,  R₁ – R₂	p value
	Site no.	Province	Cities	Study sites with LPM interventions, R₁	Reference sites without LPM interventions, R₂	Difference in reduction,  R₁ – R₂	p value

*Similar seasonal patterns of absolute humidity had been observed among study sites with and without closures (e.g., study site 1–6, site 14, site 17, and reference site 1). LPM, live poultry market.
