Results (acc. to author)

Mobile phone use for calls was low: 417 children did not use mobile phones, and only 10% of the user made 10 or more calls per week. Cordless phones were used by 470 children, of these 6% made 10 or more calls per week.
Only 5 of 78 results of phone use with cognitive measures were statistically significant.
The authors concluded that there was little evidence that cognitive function was associated with mobile phone and cordless phone use in primary school children.
