Randomized Controlled Trial Comparative Study Clinical Trial
Equipping the community to measure children's height: the reliability of portable instruments.
To compare (1) the reliability of two expensive and two inexpensive measuring instruments, suitable for use in the community and (2) the reliability of experienced compared with inexperienced observers. ⋯ Inexpensive height measuring equipment, once accurately installed, is no less reliable than the most expensive. Inexperienced observers can, with care, measure as reliably as those with long experience. Every effort should be made, however, to ensure that the progress of individual children is monitored not only by the same observer, but on a long term basis.
