Exclusive breastfeeding and infant colic: a systematic review and meta-analysis.
Synthesis in BMC pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe benefits of exclusive breastfeeding for infant health outcomes have been widely reported; however, its association with infant colic remains unclear. This systematic review and meta-analysis aimed to examine whether exclusive breastfeeding is associated with lower odds of infant colic.
methodsWe searched MEDLINE via OVID, EMB Reviews, Embase, MIDIRS, and Global Health for relevant publications up to March 8, 2026. We included observational studies reporting infant colic among exclusively breastfed infants compared with infants receiving other types of feeding (mixed feeding, formula feeding, or non-exclusive breastfeeding) in children under 12 months of age. Two authors independently screened studies using Covidence, assessed risk of bias, and extracted data using Excel. Overall pooled estimates were obtained using multilevel random-effects meta-analysis, and subgroup analyses were conducted using multilevel meta-regression models, with additional stratified random-effects models for comparator-specific estimates.
resultsOf 13,349 articles identified, 15 studies involving 216,314 infants were included in the meta-analysis. Exclusively breastfed infants had 19% lower odds of colic than non-exclusively breastfed infants (pooled OR = 0.81, 95% CI: 0.67-0.97, p = 0.021). Substantial heterogeneity was observed across studies (I² = 92.6%). Additional analyses suggested that the pooled estimate was robust and unlikely to be substantially affected by publication bias or small-study effects. In subgroup analyses, exclusive breastfeeding was associated with a significantly lower likelihood of infant colic relative to mixed feeding (OR = 0.72, 95% CI: 0.57-0.93; p = 0.01). However, the association was weaker and not statistically significant when exclusive breastfeeding was compared with formula feeding (OR = 0.92, 95% CI: 0.71-1.17; p = 0.470).
conclusionsExclusive breastfeeding was associated with lower odds of infant colic. Further high-quality studies are needed to address limitations in the existing evidence and to better understand the mechanisms underlying this association.
