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

Background: Studies have reported that the age at natural menopause may vary between different ethnic groups. Chinese Han and Tibetan women exhibit substantial differences in their living environment, dietary habits, and lifestyle; however, few studies have specifically investigated the potential differences in their age at natural menopause. This study was designed to identify the discrepancy in the age at natural menopause between postmenopausal women of Chinese Han and Tibetan ethnicities. Methods: A cross-section study has been conducted on 5,562 Han and 1,049 Tibetan postmenopausal women who were recruited by the China Multi-ethnic Cohort study from May 2018 to September 2019. The participants have resided in Chengdu City and Aba Prefecture, respectively, with ethnicity set as the primary exposure variable. Linear and multinomial logistic regression model was used to assess the association of the age at natural menopause with influencing factors and odds ratios for the association between premature ovarian failure, early and late menopause with the ethnicity, and influencing factors. Results: The mean age at natural menopause of Han women was 0.74 year earlier than Tibetan women ( Conclusions: The age at natural menopause of Chinese Han women was earlier than that of Chinese Tibetan women. Demographic, lifestyle, dietary habits, and reproductive factors may influence the age at natural menopause.
