Association Between Maternal Working Status and Unintentional Injuries Among 3 to 4-Month-Old Infants in Japan.
Article in Maternal and child health journal, 2021. 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
objectivesGlobally, unintentional injuries are one of the leading causes of infant death. Established risk factors for injuries during infancy include single parent households, socioeconomic disadvantage and maternal postpartum depression. We sought to examine whether maternal working status is associated with unintentional injury among infants in Japan.
methodsWe used data from an original questionnaire targeting mothers who participated in a 3 or 4-month health check-up program in Aichi prefecture, Japan. Experience of any type of unintentional injury was used as the primary outcome, and we also examined the experience of "falls" and "near-drowning" as secondary outcomes. We conducted multivariable logistic regression analysis, adjusting for covariates. We also performed propensity score matching in order to balance covariates between paid employment and unpaid employment groups.
resultsAmong 6,465 valid responses (response rate, 67%), 9.8% of infants experienced unintentional injuries. After matching on propensity for maternal employment (based on 26 covariates), we found that infants of mothers in paid employment were 1.35 times (95% CI: 1.04-1.74) more likely to experience injures, including 1.60 times higher likelihood of falls (95% CI: 1.14-2.24). Near-drowning was not significantly associated with maternal employment. We also found that father's employment status was positively associated with risk of falls.
conclusionBoth multivariable logistic analysis and propensity score matching analysis revealed that maternal paid employment status was associated with unintentional injuries among Japanese infants. To prevent infant injuries, comprehensive support for working families should be considered.
