Declines in Non-marital Births Among Black Women Between 2004 and 2014: Are Recent Trends the Result of Increases in Contraception?

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
Non-marital birth rates for women in their twenties began declining in 2008, but the mechanisms driving this decline are not yet well understood. Using a proximate determinants of fertility framework and decomposition techniques, we consider the importance of changes in relationship status, contraceptive use, and other dimensions of deliberate fertility control in understanding trends in the non-marital fertile pregnancy rate between 2004 and 2014. We use data from several cycles of the National Survey of Family Growth to identify relationship and contraceptive use status at the time of conception for pregnancies that resulted or were likely to result in live births (i.e., fertile pregnancies), and focus our analysis on non-Hispanic Black women in their twenties. We find that changes in relationship status and sexual activity did not contribute to the decline in fertile pregnancy rates, nor did changes in the distribution of contraceptive method use. Instead, changing fertile pregnancy rates within contraceptive use categories, including among those who report using no method of contraception, account for the observed trend. Though contraceptive method mix is an insufficient explanation for recent trends, our results suggest that considering the sources of within-method variation in fertile pregnancy rates over time is key to understanding declines in non-marital births, and that some women not using contraception likely engaged in a form of deliberate fertility control not captured by the National Survey of Family Growth.
