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
introductionPremarital sexual intercourse (PSI) predisposes never-married women to unwanted pregnancy, abortion, sexually transmitted infections, HIV/AIDS, and high rates of school dropout. This study examines changes and predictors of PSI among never-married women (15-24) in Nigeria.
methodsThe study used a 15-year duration of three wave's pooled individual recode (IR) dataset of the Nigeria Demographic and Health Surveys (NDHS) of 2008, 2013, and 2018. A weighted sample size of 23,446 never-married young women was analysed using frequency tables, charts, and multilevel binary logistic regression.
resultsThe prevalence of PSI among never-married women (15-24) over the 15-year duration of 3 waves of NDHS datasets was 31.3% [95%CI: 30.3, 32.3] in Nigeria. Prevalence of PSI steadily decreased from 36.8% in 2008 to 31.7% in 2013 and 26.6% in 2018. A 5-year percentage change between 2008 and 2013 showed that PSI declined by 13.2%, 16.2% between 2013 and 2018, and 27.7% over 10 years (2008-2018). Never-married women aged 20-24 had higher odds (OR= 7.8, 95%CI [6.9, 8.8], p < 0.001) of engaging in PSI than those aged 15-19. The community's knowledge of modern methods, literacy level, socio-economic status, education, religion, region of residence, employment status, and exposure to mass media were strongly associated with PSI. The intra-class correlation value of 10.1% indicates that contextual factors significantly explained the variations in PSI between clusters. The proportional change in variance of 41.3% explained the variability in the odds of PSI explained by each model with more terms.
conclusionThis study established a steady decrease in the prevalence of PSI among never-married women (15-24) over the 15-year duration of 3 waves of NDHS datasets (2008, 2013, and 2018). Thus, we conclude that concerted efforts are required to empower young women to contribute to a further reduction in PSI to improve the general national health status of women and to ensure progress towards achieving a reduction in early pregnancies among unmarried women in Nigeria.
