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

The role of estradiol in depression and Alzheimer's disease - brain disorders that disproportionately affect females - is debated. Results from observational studies are inconsistent and limited by confounding and reverse causation. To overcome these limitations, we perform two-sample Mendelian randomization. We run genome-wide association studies on sex-specific brain age gap, a proxy of brain health, and female-specific estradiol levels using data from the UK Biobank. We test for causal links between genetically-predicted factors related to estradiol exposure (estradiol levels in pre- and postmenopausal samples, reproductive span, age at menarche, age at menopause, number of childbirths) and brain age gap, Alzheimer's disease and depression as outcomes. We replicate our analyses on estradiol levels in males. Here, we find no significant associations between estradiol exposure and brain health across samples and robust methods, indicating an absence of constant causal effects and suggesting that hormonal fluctuations may drive links between estradiol and brain health.
