    On Second Thought: Finding the best way to protect kids

On September 20 powerful Maria tore across Puerto Rico, destroying homes, shattering the island's rickety power grid and phone network, and leaving its 3.4 million residents in the dark and incommunicado. Since the hurricane struck at least 212,000 people have traveled from Puerto Rico to Florida -- mainly central Florida, according to figures from the State Emergency Response Team (SERT). / AFP PHOTO / Ricardo ARDUENGO / TO GO WITH AFP STORY By Leila MACOR, Big changes for Florida with mass Puerto Rican immigrationRICARDO ARDUENGO/AFP/Getty Images

    Parents are barraged with advice about how to protect their kids — and are made to feel guilty for not following it. But what happens when the studies behind that advice turn out to be iffy? A 2007 paper in the journal Injury Prevention helped shape influential guidelines on how to position kids riding car seats. The researchers found that kids whose seats faced backwards were far less likely to be injured in a crash than those in forward-facing seats. The effect was so dramatic — a five-fold difference, according to the authors — that in 2011 the American Academy of Pediatrics said children under 2 should ride in rear-facing seats, a year longer than in previous recommendations from the group.

    Not so fast. The article has now been retracted and replaced with a new version, after statisticians found flaws in the original analysis. Although rear-facing seats do seem safer, the effect is much less impressive than the first article claimed. Sometimes the experts do get certain things backwards.
