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

backgroundBoth age of menarche and menopause are associated with impaired lung function. However, there is limited data on the association between reproductive lifespan (RL) and lung function. This study aims to evaluate the association between RL and lung function among postmenopausal women.

methodsIn the Korean National Health and Nutrition Examination Survey (2010-2015), an annual cross-sectional survey of a national representative sample of non-institutionalized Korean population, the postmenopausal women aged 40-64 years who underwent spirometry were included. Spirometry was performed according to the recommendations of the American Thoracic Society and European Respiratory Society, and RL (years) was calculated by subtracting the age at menarche from age at menopause.

resultsAmong 3,410 postmenopausal women, the mean RL were 34.91 (standard error 0.07). In spline regression models, shorter RL was associated with reduced predicted forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV

conclusionsIn postmenopausal women, a shorter RL was associated with abnormal lung function, particularly with a restrictive ventilatory disorder.
