The New York Times gets taken to Gary Schwitzer's woodshed for a story about a study on coffee consumption and oral cancer deaths. It's not that the story wasn't accurate, Schwitzer writes on HealthNewsReview.org. But it should have emphasized that such "observational" studies cannot show cause-and-effect relationships: "Please, Grey Lady, don’t let your writers contribute to the back-and-forth ping-pong games of 'coffee lowers risk,' 'coffee heightens risk' stories."
