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

backgroundInfertility poses a significant burden on both global and national scales. However, the epidemiology of primary infertility among reproductive-aged couples in China remains poorly understood. Therefore, this study aimed to investigate the global infertility rate and identify factors associated with primary infertility among middle-aged couples in China.

methodsCross-sectional data were derived from the Global Burden of Disease (GBD) study and the Chinese Health and Retirement Longitudinal Study (CHARLS), two extensive databases that examined various disease burdens and associated factors at both global and national levels.

resultsFrom 1990 to 2019, the global infertility population has shown a steady annual increase. In China, the age-standardized prevalence rate of infertility has remained relatively stable over the past three decades. However, this rate was notably higher than the global age-standardized infertility prevalence rate. Our analysis revealed that the prevalence of primary infertility among middle-aged Chinese couples was approximately 1.7% (947,953/56,892,517). Additionally, we identified anxiety as an associated factor with infertility, highlighting the need for increased public attention to mental health in China.

conclusionsInfertility continued to be a pressing issue on both global and national levels. This situation warranted widespread attention from Chinese policymakers and healthcare managers. The findings might guide future policy-making and medical interventions in China, with a particular focus on supporting the reproductive needs of middle-aged individuals.
