Other trials evidenced instead positive results with zinc supplementation in acute respiratory infections: in 2011, Valavi et al. [257] described a faster resolution of symptoms in zinc-supplemented children; in 2012, a lower mortality rate was evidenced in Uganda in children who received zinc supplementation during the acute infection [261]; in 2019, Acevedo-Murillo and colleagues [266] reported a quicker improvement in the clinical status of pneumonia pediatric patients receiving zinc supplementation; in a Thailandese 2019 trial, zinc supplementation was associated with a shorter hospital stay and quicker resolution of symptoms [267].
