1 · What the graph read from it

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.

2 · The registry

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

backgroundWomen with polycystic ovary syndrome (PCOS) face breastfeeding challenges. We aimed to compare exclusive breastfeeding rates in women with PCOS to those in a population-based cohort, and to explore the effect of metformin and metabolic factors on exclusive breastfeeding in women with PCOS.

methodsThis cohort study included 653 women from the pilot, PregMet, and PregMet2 randomized trials on metformin in pregnant women with PCOS (2000–2017), and 63,927 women from the Norwegian Mother, Father and Child Cohort Study (MoBa) (1999–2008) as the reference group. Logistic regression estimated odds ratios for exclusive breastfeeding one month postpartum in women with PCOS versus MoBa women, and in women with PCOS randomized to metformin or placebo.

resultsWomen with PCOS reported less exclusive breastfeeding than MoBa women one month postpartum (adjusted OR (aOR) 0.52 (0.42–0.63)). Among women of normal weight, those with PCOS breastfed to the same extent as MoBa women (aOR 0.98 (0.63–1.54)), but less in the overweight or obesity categories (aOR 0.56 (0.39–0.82) and aOR 0.55 (0.40–0.76), respectively). However, differences across weight categories were not statistically significant (p-value for interaction = 0.088). We found no difference in exclusive breastfeeding between metformin and placebo-treated women with PCOS. Hypertensive disorders and gestational diabetes did not affect exclusive breastfeeding rate in PCOS.

conclusionsExclusive breastfeeding did not differ between normal weight women with PCOS and women from the MoBa study. Among women with high BMI, women with PCOS breastfed less exclusively than MoBa women. In PCOS, neither metformin treatment, hypertension nor gestational diabetes affected exclusive breastfeeding.
