Reply to Letter to Editor: Hydroxychloroquine Blood Levels Predict Hydroxychloroquine Retinopathy

AbstractThese observed relationship between HCQ blood levels and risk of toxicity in these results is very similar to what we presented in the published paper.Second, we used logistic regression to determine whether there was still a statistically significant association between mean HCQ blood levels and retinopathy after adjusting for duration of time on HCQ. The results were similar to those seen in the paper and above (P ‐value=0.016, p‐value for trend=0.003 after adjustment).
