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

purposeMost studies have reported that the risk of coronary heart disease decreases when menopausal hormone therapy (MHT) is initiated before the age of 60 years or within 10 years of menopause. However, the findings regarding stroke risk remain conflicting. This study investigated the association between the risk of ischemic stroke and MHT, categorized by the type of MHT. MATERIALS AND

methodsThis population-based, retrospective cohort study was based on the Korean National Health Insurance Service-National Sample Cohort (2004-2015). Participants were aged 45-60 years with no cardiovascular disease or preexisting stroke, classified as never, past, and current users of MHT.

resultsAmong the study participants, 16915 (88.77%) women had never undergone MHT, 1437 (7.54%) had previously undergone MHT, and 703 (3.69%) were currently using MHT. During the study period, with a mean follow-up of 11.23±2.13 years, the risk of ischemic events was significantly higher among current users [hazard ratio (HR): 2.98, 95% confidence interval (CI): 1.95-4.57,

conclusionWomen currently receiving MHT without underlying cardiovascular disease exhibited an increased risk of ischemic stroke, particularly those treated with E-only MHT or tibolone. However, this increased risk returned to baseline after discontinuing MHT, indicating that past use of MHT was not associated with an increased risk of ischemic stroke.
