A validation of the PAWPER XL-MAC tape for total body weight estimation in preschool children from low- and middle-income countries.

The PAWPER XL-MAC tape performed well in this study and was statistically significantly more accurate than both the Broselow tape editions and the Ralston method. This difference was substantial and clinically important. The tape did not perform as well at extremes of habitus-type, however, and might benefit from recalibration.
