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

objectiveWe investigated the frequencies and characteristics of out-of-hospital births in a 20-year period in California, where 1 of every 7 births in the United States occurs. STUDY

designBirth certificate records of deliveries in California between 1991 and 2011 were analyzed. Out-of-hospital births were assessed by year, parity, gestational age and maternal race/ethnicity.

resultsIn the 20-year period there were 10 593,904 deliveries, of which 46 243 occurred out of hospital (0.44%). Out-of-hospital births decreased from 0.54 to 0.38% per year between 1991 and 2004, and increased from 0.41% in 2005 to 0.61% in 2011. In contrast, preterm out-of-hospital births declined from 7.2% in 2006 to 5.0% in 2011. The frequency of vaginal birth after cesarean in the out-of-hospital birth cohort increased from 1.2% (n=19) in 1996 to 4.2% (n=82) in 2011.

conclusionCalifornia birth records from a 20-year period show an increase in out-of-hospital births from years 2005 to 2011, following a period of decline from 1991 to 2004.
