The intervals from exposure of thallium to diagnosis were converted into days. One week = 7 d; One month = 30 d. The recent exposure was chosen for this study in the patients with multiple intoxications. Cases were grouped according to the outcomes described in the original papers: Death, severe sequelae (need assistance with daily activities), and mild sequelae (independent for daily activities).
