INTRODUCTION infantile colic has always been a problem for caregivers, and research on probiotics in treating and preventing infant colic is still controversial. MATERIAL AND METHODS trials were performed before November 2021 and retrieved from the PubMed, Web of Science, The Cochrane Library, Medline, and Google Scholar databases. Data extraction and quality evaluation of the trials were performed independently by two investigators. A meta-analysis was performed using Review Manager 5.3. It includes nine randomized controlled trials in 587 infants with colic. RESULTS eight of these experiments described probiotics for the prevention and treatment of intestinal colic in infants, with 228 in the probiotics group and 227 in the placebo group, with a total effective rate (RR = 1.88, 95 % CI: 1.61 to 2.19, p < 0.00001). CONCLUSION probiotics may improve therapeutic and preventive effects, especially within four weeks of probiotic treatment.
