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

objectiveTo estimate the duration of moderate-to-severe menopausal hot flushes and identify potential risk factors for hot flush duration.

methodsThe Penn Ovarian Aging Study cohort was monitored for 13 years. Hot flushes were evaluated at 9-month to 12-month intervals through in-person interviews. The primary outcome was the duration of moderate-to-severe hot flushes estimated by survival analysis (n=259). Potential risk factors included menopausal stage, age, race, reproductive hormone levels, body mass index (BMI), and current smoking. A secondary analysis included women who reported any hot flushes (n=349).

resultsThe median duration of moderate-to-severe hot flushes was 10.2 years and was strongly associated with menopausal stage at onset. Hot flushes that started near entry into the menopause transition had a median duration greater than 11.57 years; onset in the early transition stage had a median duration of 7.35 years (95% confidence interval [CI] 4.94-8.89; P<.001); and onset in the late transition to postmenopausal stages had a median duration of 3.84 years (95% CI 1.77-5.52; P<.001). The most common ages at onset of moderate-to-severe hot flushes were 45-49 years (median duration, 8.1 years; 95% CI 5.12-9.28). African American women had a longer duration of hot flushes than white women in adjusted analysis.

conclusionThe median duration of hot flushes considerably exceeded the timeframe that is generally accepted in clinical practice. The identified risk factors, particularly menopausal stage, race, and BMI, are important to consider in individualizing treatment and evaluating the risk-to-benefit ratio of hormones and other therapies.
