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

objectiveTo explore time trends in abortion based on method used and characteristics associated with method type by uniquely linking social and behavioral data reported by a population-based cohort of young Australian women.

methodsWe analysed self-reported data from 16 993 women in the Australian Longitudinal Study on Women's Health 1989-95 cohort, aged 18-24 years at recruitment in 2013, linked to abortion data from three population-based administrative data sources.

resultsThe incidence of medication abortion increased over time whereas surgical abortion decreased, with similar trends across the largest states. The adjusted odds ratio (AOR) of having a medication compared with a surgical abortion increased over time [by each 1-year increase in time, 1.33 (95% confidence interval 1.20, 1.48)]. Women who lived in outer regional/remote/very remote areas [AOR 3.51 (2.15, 5.74)] and inner regional areas [1.80 (1.21, 2.69)] had increased odds of a medication abortion compared with women who were living in major cities. Medication abortions were more common than surgical abortions in outer regional/remote/very remote areas from 2017 whereas, in major cities, surgical abortion remained the most common abortion method throughout the study period.

conclusionLinkage of government-recorded health events with self-reports demonstrated a shift towards increasing use of medication abortion relative to surgical abortion, with greater increases in nonmetropolitan areas. The strong geographical disparities in abortion method suggest that, for those who are living in nonmetropolitan areas, there may be less opportunity to choose surgical abortion due to limited availability of services, with significant implications for women who present later in pregnancy.
