Risk factors for and protective factors against breastfeeding interruption before 2 years: a birth cohort study.
Article in BMC pediatrics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundLittle is known about the factors associated with the World Health Organization (WHO) recommendation of breastfeeding for at least 2 years. The objective of this study was to identify risk factors for and protective factors against breastfeeding interruption before 2 years of age.
methodsIn this live birth cohort, mother and infant dyads were followed for 2 years. Data collection was performed at the maternity ward and subsequently at the children's homes, monthly during the first 6 months of life and then at 9, 12, 18, and 24 months. The outcome of interest was breastfeeding interruption before 2 years of age. Median duration of breastfeeding was estimated using Kaplan-Meier's survival analysis, and the associations were tested using Cox's hierarchical multivariate model. Significance was set at 5%.
resultsData from a total of 1344 dyads were assessed. Median breastfeeding duration was 385 days. The following risk factors for breastfeeding interruption were identified: white skin color (adjusted hazard ratio [HRa]: 1.31; 95% confidence interval [95%CI]: 1.10-1.56), primiparity (HRa: 1.21; 95%CI: 1.05-1.40), working outside the home (HRa: 1.52; 95%CI: 1.30-1.77), child sex male (HRa: 1.18; 95%CI: 1.03-1.35) and use of a pacifier (HRa: 3.46; 95%CI: 2.98-4.01). Conversely, the following protective factors were identified: lower family income (HRa: 0.81; 95%CI: 0.71-0.94), mother-infant bed-sharing (HRa:0.61, 95%CI: 0.52-0.73), on-demand breastfeeding in the first month (HRa: 0.64; 95%CI: 0.47-0.89) and exclusive breastfeeding at 4 months (HRa: 0.58, 95%CI: 0.48-0.70).
conclusionsThe findings allowed to identify both risk factors for and protective factors against breastfeeding interruption before 2 years of age. Knowledge of these factors may help prevent this event and aid in the development of programs that help women maintain breastfeeding for at least 2 years, as recommended by the WHO.
