    Response to Chris J Kalman

    June 8th 2009

    We are writing to respond to Dr.Kalman in regard to our article entitled “Maternal Occupational Exposure and Risk of Spontaneous Abortion in Veterinary Practice”.

    Regarding the risk relating to radiation, we presented data separately for those with 1-4 x-rays a week in Table 2. Readers are able to use these analyses rather than those in Table 3 if they prefer. The results for exposure...

    Shirangi and her colleagues set out to examine the relationship between occupational exposures and spontaneous abortion in female veterinarians. One exposure examined, is in relation to the use of x- rays, where the authors report in the abstract that veterinarians who reported performing more than 5 radiographic examinations per week had a statistically significant elevated risk of spontaneous abortion compared with th...
