Preventing Pregnancy in High School Students: Observations From a 3-Year Longitudinal, Quasi-Experimental Study.
Article in American journal of public health, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled 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.
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
objectivesTo assess whether a sexual health education intervention reduces pregnancy rates in high school students.
methodsWe performed a secondary analysis of a 3-year quasi-experimental study performed in South Texas from 2011 to 2015 in which 1437 students without a history of pregnancy at baseline were surveyed each fall and spring. Potentially confounding risk factors considered included sexual behaviors, intentions, and demographics. The outcome measure was self-reported pregnancy status for male and female students. We performed analyses for male and female students using separate discrete time-to-event models.
resultsWe found no difference in pregnancy rates between intervention and comparison students within the first 3 years of high school. Female and male students in the intervention groups had pregnancy hazard ratios of, respectively, 1.62 (95% CI = 0.9, 2.61; P = .1) and 0.78 (95% CI = 0.44, 1.48; P = .4) relative to the comparison groups.
conclusionsThe educational intervention had no impact on the pregnancy rate. Social media tools in pregnancy prevention programs should be adaptive to new technologies and rapidly changing adolescent preferences for these services.
