Table 1.

Summary of insertion angles from multiple studies using multiple electrode arrays. Units for Mean, Standard Deviation (SD), Median, Minimum insertion angle (Min), Maximum insertion angle (Max), and Range of insertion angles are degrees. Results are organized by manufacturer. Within manufacturer, results are sorted by mean insertion depth for the corresponding study.
