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

backgroundIt is unknown whether cognitive status or diagnosed cognitive decline affects estrogen use.

objectivesWe assessed how common systemic estrogen use was among community-dwellers with Alzheimer's disease (AD) and a matched comparison cohort without AD.

methodsThis study included an exposure-matched cohort of all Finnish community-dwelling women who received a clinically verified diagnosis of AD in 2005-2011 (N = 46,116; index cases) and an equally sized matched comparison cohort without AD. Follow-up began on the matching date (date of the AD diagnosis of the index case). Data on systemic estrogen use were obtained from the prescription register. Use initiation and discontinuation were assessed.

resultsAltogether 3.1% of women with AD and 4.3% of women without AD used estrogen during the follow-up period. Only < 0.5% initiated use during the follow-up period, but 3.7% continued use until death. The prevalence of estrogen use 1 year after the AD diagnosis declined in 2005-2011.

conclusionsThere were no major differences in systemic estrogen use among Finnish women with AD when compared to those without AD. Although some persons initiated estrogen use after AD diagnosis and/or at an advanced age, the observed use patterns were mainly consistent with the current recommendations.
