We read with great interest the article by Ladinsky et al1 that compared parental satisfaction with a packet-based oral rehydration solution (WHO-ORS) to satisfaction with a commercially prepared oral rehydration solution (C-ORS).
We are concerned about the satisfaction data reported in Table 5. The authors report that 97 families were initially enrolled in this randomized controlled trial and 91 families actually completed the follow-up interview. In the table, the C-ORS group has 50 respondents and the WHO-ORS group has 47 respondents for a total of 97. It is unclear why families that did not complete follow-up surveys were included in this analysis.
