Fig. 4. P100 latencies, (A) before and (B) at the end of interferon treatment, plotted against patients’ age. Data from 74 eyes (45 patients) with normal pretreatment visual evoked responses. (B) Note the steep increases of P100 latency in patients past the 5th decade of age at the end of interferon therapy only. Curves represent a best fitted cubic regression line ± 95% confidence intervals.
