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 registryThe 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.

6 · The paper itselfAbstract
We examined whether severe maternal morbidity (SMM) at delivery was associated with the initiation and duration of breastfeeding among nulliparous individuals in the United States in a secondary analysis from the prospective nuMoM2b-HHS (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be Heart Health Study). Among 6,762 nulliparous individuals, the frequency of any breastfeeding by duration was as follows: 759 (11.2%) breastfed for less than 6 weeks; 1,847 (27.3%) breastfed for 6 weeks to 6 months; and 3,359 (49.7%) breastfed for more than 6 months, and the frequency of exclusive breastfeeding among those with any breastfeeding was 4,653 (85.4%). The frequency of any SMM was 160 (2.4%) and nontransfusion SMM was 124 (1.8%). Breastfeeding initiation did not vary by SMM status. Among those who breastfed, SMM was associated with a lower likelihood of breastfeeding for more than 6 months (adjusted odds ratio [aOR] 0.50; 95% CI, 0.36-0.68) and a lower likelihood of exclusive breastfeeding (aOR 0.60; 95% CI, 0.37-0.98). In a prospective cohort of nulliparous pregnant individuals from across the United States, SMM at delivery was not associated with breastfeeding initiation, but was associated with a significantly lower likelihood of breastfeeding duration and exclusive breastfeeding.
