Estimated effect of teenage pregnancy on adverse birth outcome in Sub-Saharan African countries: propensity score matching analysis of recent demographic and health survey data.

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
introductionGlobally adverse birth outcome is being a series public health problem. As studies showed, even though the etiologies are multifactorial, extreme age pregnancies have more risk for adverse birth outcome. This study determines the estimated effect of teenage pregnancy on adverse birth outcome.
methodThe study analyzed data from the most recent Demographic and Health Surveys (DHS) data. Propensity score matching (PSM) analysis was employed by using age as treatment variable, teenager as treated and non-teenagers as control group and weighted sample of 45,790 (non-teenagers = 41,769 and teenagers = 4,021). The outcome variable; adverse birth outcome was categorized as "Yes" if a woman had either preterm birth, still birth, low birth weight or macrosomia in her recent birth and "No" otherwise. Covariates that had significant association with the treatment and outcome variables were considered for PSM analysis. After testing of each matching techniques (nearest neighbor, kernel and radius), the nearest neighbor (10) approach produced better covariate balance and selected as the best matching algorism for our analysis. Finally, the effect of teenage pregnancy on adverse birth outcome was measured and reported as average treatment effect on the treated (ATT) and the quality of matching and sensitivity to hidden bias was assed by t-statistics significance level and Mantel-Haenszel statistic respectively.
resultsThis study found that around one in ten (8.7%) of the women had pregnancy between the age of 15 and 19 years. The magnitude of adverse birth outcome among teenagers and non-teenagers was also 45.4% and 39.9% respectively. Teenage pregnancy contributed to a 4.7% increasing adverse birth outcome (ATT = 4.7%). Similarly, the Average Treatment Effect on Untreated (ATU) was 4.8%.
conclusionThis study revealed that around one in teen women had pregnancy between the age of 15 and 19 years and teenage pregnancy had more risk of having adverse birth outcomes as compared to non-teenagers. Thus, we recommend to policy makers and implementers to design policies and strategies to improve teenagers' access to prenatal care, family planning, and sexual education, awareness of creation on teenage pregnancy risks.
