Figure 1. Weekly lot-specific observed and predicted attack rates (cases/1,000 mL injected) for illness among persons injected from 3 lots of methylprednisolone acetate (MPA) contaminated with the fungus Exserohilum rostratum, United States, 2012. Observed rates obtained by combining single injection data and 1 representative multiple injection simulated dataset (observed rates for multiple injections varied by simulation). Observations after September 23, 2012, were excluded in the prediction model. Long-dashed line indicates the date of the recall of the 3 lots of MPA (September 26, 2012); short-dashed line indicates the boundary of reliable estimates of attack rates in our model (October 14, 2012).
