Primary care of mothers and infants by the same or different physicians: a population-based cohort study.
Article in CMAJ : Canadian Medical Association journal = journal de l'Association medicale canadienne, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundDifferent primary care delivery models exist for mothers and their infants. We examined whether primary care system performance measures differed when mother-infant dyads received primary care from the same or different providers.
methodsWe conducted a population-based cohort study using Ontario health administrative data from 2004 to 2016. We included primiparous women and their singleton term infants and classified the primary care practitioners who provided the majority of care to the infant and the mother as concordant (same family physician for both; reference group), discordant (a different family physician for each) or pediatrician (pediatrician for the child, family physician for the mother). The primary outcome was nonobstetric maternal hospital admissions between 42 days and 2 years after delivery.
resultsAmong 481 721 mother-child pairs, 239 033 (49.6%) received concordant care, 114 006 (23.7%) received discordant care, and 128 682 (26.7%) received pediatrician care. Mothers in the pediatrician group were older and had greater comorbidity. Relative to concordant care, maternal nonobstetric hospital admissions occurred similarly under discordant care (adjusted odds ratio [OR] 1.00, 95% confidence interval [CI] 0.96-1.04) and in the pediatrician group (adjusted OR 0.99, 95% CI 0.95-1.02). Maternal deaths were similar under discordant care (adjusted OR 1.00, 95% CI 0.62-1.63) but lower in the pediatrician group (adjusted OR 0.55, 95% CI 0.34-0.89). Maternal primary care visits were lower in both the discordant group (adjusted relative risk [RR] 0.68, 95% CI 0.68-0.69) and the pediatrician group (adjusted RR 0.75, 95% CI 0.75-0.76). Healthy children were more likely to miss the enhanced 18-month well-baby visit under discordant care (adjusted OR 1.06, 95% CI 1.03-1.09) but less likely to miss this visit under pediatrician care (adjusted OR 0.47, 95% CI 0.46-0.49).
interpretationConcordant care provided to a new mother and her infant by the same family physician was not associated with better primary care health system performance. The reason that pediatric primary care is associated with better maternal and child outcomes remains to be determined.
