RT Journal A1 Ballew C, Kuester S, Gillespie C T1 THe necessity for statistical precision—reply JF Archives of Pediatrics & Adolescent Medicine JO Archives of Pediatrics & Adolescent Medicine YR 2001 FD May 1 VO 155 IS 5 SP 619 OP 620 DO 10.1001/archpedi.155.5.618 UL http://dx.doi.org/10.1001/archpedi.155.5.618 AB Dr Baker is correct in pointing out that the OR should be raised to a power of 8 rather than multiplied by 8 to extrapolate from 1 oz of a beverage to 8 oz of a beverage. This change in no way alters the interpretation of our results, that drinking a glass of milk has a very profound positive effect on calcium intake, and drinking a glass of a carbonated bev erage has a small but nevertheless statistically significant negative effect. In fact, the corrected extrapolations make our point even more strongly.
