Figure 3.

Proportion of arrays exceeding a certain yield at month-to-month intervals post-implantation. Each line delineates a different percentage yield threshold. If an array is not recorded from in a given time window, it is not counted in the “proportion” estimate. After their last available recording date, arrays are counted in the proportion measurement, to accurately depict the degradation of arrays on average. However, arrays which ceased recording due to medical, hardware failure, or study end reasons (see Table 1) were not included in the proportion measurement after their last available recording date.
