Fig 2.
Percent intracranial AEs per patient.
The rate of AEs is color-coded. The number of patients that have been included in respective studies are indicated by the height of the wedges (cutoff value 500 patients).
Fig 3.
Percent hardware removal per patient.
The rate of AEs is color-coded. The number of patients that have been included in respective studies are indicated by the height of the wedges (cutoff value 500 patients).
Fig 4.
Percent hardware removal per patient-year.
The rate of AEs is color-coded. The number of patient-years calculated for individual studies is indicated by the height of the wedges (cutoff value 1000 patient-years).
Fig 5.
Percent lead revision per patient.
The rate of AEs is color-coded. The number of patients that have been included in respective studies are indicated by the height of the wedges (cutoff value 500 patients).
Fig 6.
Percent lead revision per patient-year.
The rate of AEs is color-coded. The number of patient-years calculated for individual studies is indicated by the height of the wedges (cutoff value 1000 patient-years).
