Two pie charts show reported analgesic use in rats and mice in 2000–2002 after email follow-up of authors who reported no analgesic use. The chart for the original reporting shows that 67% of the studies reported no analgesia, 19% anesthetic analgesia, and 14% reported the use of analgesia. After email follow-up, the percentage of authors reporting no analgesia was 58%, anesthetic analgesia 19%, and analgesia 23%. Source: Richardson and Flecknell (2005).
