Dear Editor,

We read with interest the letter by Borszcz and de Lucas [ 1] commenting on our recent systematic review and meta-analysis [ 2] and subsequent correspondence [ 3, 4]. While we think some of the points raised by the correspondents may be insightful for readers, we have some concerns about others. We conducted our systematic review and meta-analysis assuming that carryover effects would be negligible in carbohydrate (CHO) mouth rinse study designs given the nature of treatment and washout usually observed between trials, and that the use of the standardized mean difference (SMD) and standard error (SE) suggested for parallel group designs should be conservative when identifying eventual beneficial CHO effects on performance [ 5]. However, crossover designs have advantages because each participant works as his/her own control so that more power is obtained with the same number of participants when compared to parallel group studies [ 6]. Therefore, we agreed with Borszcz and de...
