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
backgroundAlzheimer's disease is more prevalent in women than in men. In this study, the author examined the U.S. Food and Drug Administration (FDA) completed phase 4 clinical trials associated with Alzheimer's. The research aims to evaluate the women's participation-to-prevalence ratio (PPR) for Alzheimer's disease.
methodUsing the FDA's publicly available clinical trial database, 45 Phase 4 Alzheimer's trials from 2003 to 2019 were assessed. Further, the total PPR and yearly PPR value are calculated by dividing the percentage of women in clinical trials by the total percentage of women affected by Alzheimer's disease. The PPR value equal to 1 showcases the balanced participation of females in the Phase 4 clinical trial and the diseased affected population.
resultOut of 45 trials, 41 were completed and four were terminated. The gender data was unavailable for three trials. In 38 clinical trials associated with Alzheimer's disease, 4502 participants were enrolled. Among 4502, 2604 (57.84%) were found to be female and 1898 (42.15%) were male. The PPR for women was 0.80, reflecting an adequate representation of women participants in late-phase clinical trials. The yearly PPR reduction has been seen in female participants.
conclusionIn the year-based PPR, the range was from 0.72-1.0. In the initial year, the range was 1, which was reduced to 0.72 in 2007. In total, 38 completed clinical trials, 18 trials used placebo treatment, and the gender ratio in placebo was adequate. More transparency is essential in gender concerning SAE in publicly available databases.
