2-Sample MR, COPD effect on cognitive function

Lung function measure	No. of SNPs	Test used	Cognitive function
			Beta (SE)	p-value	Q_P-value
COPD	67	IVW	− 0.008 (0.008)	0.35	0.005
		Weighted median	− 0.01 (0.01)	0.16
		Weighted mode	− 0.03 (0.02)	0.28
		MR Egger	− 0.01 (0.02)	0.66

Negative beta indicates decreasing cognitive function
