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

backgroundOut-of-hospital births have been increasing in the United States, although past studies have found wide variations between states. Our purpose was to examine trends in out-of-hospital births, the risk profile of these births, and state differences in women's access to these births.

methodsNational birth certificate data from 2004 to 2017 were analyzed. Newly available national data on method of payment for the delivery (private insurance, Medicaid, self-pay) were used to measure access to out-of-hospital birth options.

resultsAfter a gradual decline from 1990 to 2004, the number of out-of-hospital births increased from 35 578 in 2004 to 62 228 in 2017. In 2017, 1 of every 62 births in the United States was an out-of-hospital birth (1.61%). Home births increased by 77% from 2004 to 2017, whereas birth center births more than doubled. Out-of-hospital births were more common in the Pacific Northwest and less common in the southeastern states such as Alabama, Louisiana, and Mississippi. Women with planned home and birth center births were less likely to have a number of population characteristics associated with poor pregnancy outcomes, including teen births, smoking during pregnancy, obesity, and preterm, low birthweight, and multiple births. More than 2/3 of planned home births were self-paid, compared with 1/3 of birth center and just 3% of hospital births, with large variations by state.

conclusionsLack of insurance or Medicaid coverage is an important limiting factor for women desiring out-of-hospital birth in most states. Recent increases in out-of-hospital births despite important limiting factors highlight the strong motivation of some women to choose out-of-hospital birth.
