increased rapidly.
We used Stata/SE 15.0 for all analyses. The reporting of our study conforms to

3. Result
Observed Incidence: There was a total of 16,825 eligible brain cancer cases
aged 20 to 59 (10,083 males and 6,742 females) that were diagnosed between
1982 and 2013. The observed incidence trends (given as APC) over the time-
periods 1982-1992, 1993-2002 and 2003-2013 are shown in Table 1 for both
genders The overall brain tumour rates remained stable in all three time-
periods and the trends were similar for males and females. Glioblastoma
increased during the period that saw advances in MRI (1993-2002) whilst it
remained stable during the period of substantial mobile phone use (2003-
2013); this later period also saw a decrease in other glioma sub-types. There
was a strong decreasing trend in brain tumours with unspecified histology
during the period of increased CT and MRI use (1982-1992). With the
redistribution of unspecified tumours there were no significant changes to
these histological trends (Table 2)
