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

This study aimed to examine the effect of increases in the duration of education on sexual activity in later life using the instrumental variable approach. Cross-sectional data were obtained from the English Longitudinal Study of Ageing, Wave 6 (2012/2013) for the analysis. The effect of the duration of education on a binary variable for sexual activity in the past month was examined by two-stage least squares estimation using the 1947 schooling reform as the instrument. A total of 1493 participants were included. The 1947 schooling reform significantly extended the duration of education by a mean of 0.86 years (95% confidence interval (CI), 0.52-1.20; F = 24.70) for men and 0.81 years for women (95% CI, 0.54-1.09; F = 33.82). The second-stage regression showed that an additional year of education increased the probability of having sexual activity in the past month by 0.16 points (95% CI, 0.07-0.25) for men and decreased the probability of having sexual activity in the past month by 0.18 points (95% CI, - 0.30- - 0.05) for women. The causal mediation analysis revealed that long-standing illness mediated the mechanism between education and sexual activity, but the mediational effect was clearly observed only for men: the indirect effect for men was 0.10 (95% CI, 0.01-0.20; the proportion mediated, 78.1%) and for women was - 0.16 (95% CI, - 1.23-0.90; the proportion mediated, 97.8%), respectively. This study confirmed the causal effect of education on sexual activity. However, the effect for men and women was completely opposite.
