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

objectiveFollowing a significant relaxation of restrictions in China on December 7, 2022, after a surge in SARS-CoV-2 infections, an uptick in women presenting with menstrual disorders was observed in clinics. This study aimed to explore the alterations in menstrual characteristics and associated factors post SARS-CoV-2 infection.

methodsA cross-sectional online survey was conducted among 869 non-amenorrheic adult Chinese females (aged 18-53) to study the changes in menstrual characteristics and other infection-related factors post initial SARS-CoV-2 infection. The reported menstrual changes (group A) were compared to the reported no menstrual changes (group B). Data collected included basic individual-level information such as age, height, weight, menstrual history, reproductive and menstrual disorders, chronic diseases, SARS-CoV-2 vaccination status, COVID-19 symptoms, and changes in menstrual characteristics (regularity, period volume, and degree of dysmenorrhea) post SARS-CoV-2 infection.

resultsOf the 869 participants, 442 (50.9%, group A) reported alterations in at least one menstrual characteristic; 171 (19.7%) experienced an extended menstrual cycle, and 122 (14.0%) reported a decrease in menstrual volume. Participants who reported menstrual changes (group A) were more likely to have pre-existing chronic diseases (7.7% vs. 3.0%, P = 0.003) and exhibit more symptoms of COVID-19 during the acute (4.94 vs. 4.03, P < 0.001) and recovery (4.37 vs. 3.41, P < 0.001) phases. These participants were also more likely to report fever as a COVID-19 symptom (93.4% vs. 86.9%, P = 0.001) and experienced a longer duration of fever (2.25 vs. 1.96 days, P = 0.001) as compared to group B. Notably, group A with chronic diseases, fewer vaccine doses, and more COVID-19-related symptoms experienced more frequent menstrual changes post COVID-19 (P < 0.05) than group B.

conclusionParticipants with chronic diseases, fewer vaccination doses, and more COVID-19-related symptoms may experience more frequent menstrual changes post COVID-19 infection according to the self-report results in this study.
