Fig. 3From: A decreased risk of meningioma in women smokers was only observed in American studies rather than studies conducted in other countries: a systematic review and meta-analysisPooled OR and 95% CI for the association between never versus current or past smoking and risk of meningioma in women. Current smoking was associated with a significantly reduced risk of meningioma in women, with pooled OR of 0.78 (95% CI 0.66–0.93; P for heterogeneity, 0.229, A). Past smoking was associated with a significantly reduced risk of meningioma in women, with pooled OR of 0.82 (95% CI 0.71–0.94; P for heterogeneity, 0.679, B)Back to article page
