Wealth-related inequalities in the utilisation of modern contraceptives in Papua New Guinea: evidence from the 2016-2018 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
objectiveTo examine the wealth-related disparities in modern contraceptives use among women in Papua New Guinea.
designWe performed a cross-sectional analysis of the 2016-2018 Papua New Guinea Demographic and Health Survey data. We included 11 618 women of reproductive age in our final analysis. Percentages were used to present the results on utilisation of modern contraceptives. A concentration curve was used to summarise the cumulative use of modern contraceptives by wealth index (ranked into groups: richest, richer, middle, poorer and poorest). We used a decomposition analysis to estimate the contributions of individual factors towards wealth-related inequality in modern contraceptives use. We estimated the slope index of inequality (SII) and the relative index of inequality (RII) in modern contraceptive utilisation to provide summary evidence of inequality.
settingPapua New Guinea.
participantsWomen aged 15-49 years. OUTCOME MEASURE: Modern contraceptives utilisation.
resultsOverall, 27.5% of Papua New Guinea women used modern contraceptives. The concentration curve showed that the use of modern contraceptives was highly concentrated among women of the richest household wealth index as the concentration curve lies below the equality line. The SII (0.210, CI 0.182 to 0.239) indicates that the richest group uses more modern contraceptives. The RII depicts a relative difference of 2.044 between the richest and the poorest women in the use of modern contraceptives.
conclusionsOur study has shown that modern contraceptives use among women in Papua New Guinea is low. Women from the richest household wealth index group had the highest propensity to use modern contraceptives in comparison with those from poorer homes. The Ministry of Health and other organisations must design and carry out initiatives aimed at enhancing the availability of and use of modern contraceptives among women from less affluent backgrounds.
