Clin Exp Pediatr. 2022;65(12):589-594.   Published online October 31, 2022
· This study compared the ability of 2 probiotics to reduce and improve functional abdominal pain (FAP) in children.
· In the polymicrobial probiotic (PMP) group, 10.34% of children reported no pain; in the mono-strain probiotic (MSP) group, all patients reported low-degree pain. The mean pain score decreased significantly over time in both groups.
· The use of both PMP and MSP is recommended to reduce pain in patients with FAP.
