Message "The researchers studied the impact of car color on the risk of a serious injury in a study of more than 1,000 drivers in New Zealand between 1998 and 1999."

Out of this HUGE test of 1000 or so cars, 30 cases (5.3% of total) and 61 controls (11.3% of total) were silver. 30 accidents analyzed out of 1000 gives them this conclusion. 0.5 to 1 odds in a 95% confidence interval, gee, that can't be a coincidence, wow you're so smart. Try taking a Stats course before you run your mouth, you might learn something.
