Catcher Injuries Arent Usually the Result of Collisions: FRIDAY.

This means that fewer than 15 % of catcher injuries were the result of connection with another player. Moreover, these run-ins usually required less recovery period than other types of injury, the researchers said. Overall, catchers spent typically 50 days in the disabled list. Non-collision injuries were associated with an average recovery period of 53 days, in comparison to 39 days for colliding with another player. Nineteen injuries involved recovery periods greater than 100 times, but none of these involved a run-in between a catcher and a base runner. The most common reason behind non-collision injuries among the catchers was a blow to the head by a bat or foul ball. Overall, 28 % of catcher accidents involved the leg, 23 % included the knee and 23 % affected the shoulder. During the research period, catchers sustained 11 concussions.To reduce the risk of misclassification, we excluded all registrations that there have been a previous diagnosis of maternal epilepsy but also for which there was no history of maternal antiepileptic-drug use in the first trimester . Statistical Analysis Logistic-regression analysis was used to calculate odds ratios with Stata software, version 10. Crude odds ratios had been calculated for all registries, including those without records of valproic acid publicity. Odds ratios were modified for maternal age and the child’s 12 months of birth .
