Model		INTERPHONE - Norwegian National site 900, 1800 MHz (NMT, GSM, W-CDMA) mobile phone use and correlation with brain, acoustic nerve, parotid gland tumors
Details		Cases of glioma (n = 289), meningioma (n = 207), and acoustic neuroma (n = 45) diagnosed in Norway from 2001-2002, ages 19-69, were evaluated for correlations with mobile phone use. The authors report no association between "regular" (1 time per week for > 6 months) phone use and glioma (OR = 0.6; 95% CI 0.40.9), meningioma (OR = 0.8; 95% CI 0.51.1) or acoustic neurinoma (OR = 0.5; 95% CI 0.2-1.0). ORs were also less than 1.0 for all gliomas and acoustic neuromas with phone use up to 6 years. The authors also report a slightly increased OR for 6+ yr meningioma (OR = 1.2; 95% CI 0.6-2.2, based on 28 cases) and 6+ yr ipsilateral gliomas (OR = 1.3; 95% CI 0.8-2.1 based on 39 cases), but neither were statistically significant. Overall study findings: OR = 0.6; 95% CI 0.4-0.9 - glioma, OR = 0.8; 95% CI 0.5-1.1 - meningiomas, OR = 0.5; 95% CI 0.2-1.0 - acoustic neuroma, OR = 1.2; 95% CI 0.6-2.2 - 6+ yr meningioma, Ø ipsilateral association. The authors conclude no association from their data of any head tumors with mobile phone RF exposure, but also suggest recall bias may have affected the data.

Comments		OR of less than 1.0 for many of the tumor endpoints were hypothesized to be due to bias as the participating controls more often active mobile phone users than in the tumor cases
