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.
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
Purpose: To study the chromosome distribution characteristics in embryos of patients with missed miscarriage and analyze the risk factors of embryonic chromosomal abnormalities. Methods: Clinical data were collected from 216 hospitalised patients diagnosed with missed miscarriages who successfully underwent embryo chromosomal analysis at the Urumqi Maternal and Child Health Hospital between January 2022 and August 2024. The distribution of embryonic chromosomes was investigated, and risk factors for chromosomal abnormalities were identified using multivariate logistic regression analysis. Based on the above-described results, a nomogram prediction model was established and validated. The receiver operating characteristic curve was plotted, the area under the curve (AUC) was calculated, and the calibration curve and clinical decision curve were plotted to verify the model discrimination, calibration, and clinical practicability. Results: Our results showed that the rate of chromosomal abnormalities in patients with missed miscarriages was 66.67%; among these, trisomy 16 (45, X) and triploidy were the most common numerical abnormalities, while deletions were the predominant structural abnormality. Being underweight or overweight, insufficient or deficient in 25-hydroxyvitamin D, and having elevated thyroid-stimulating hormone levels were identified as risk factors for developing embryonic chromosomal abnormalities ( Conclusion: Chromosomal abnormalities are the main causes of missed miscarriages, with trisomy 16 and Turner syndrome being the most common among these. A close correlation between weight in women and embryonic chromosomal abnormalities was observed. Vitamin D deficiency or insufficiency and elevated thyroid-stimulating hormone levels may also contribute to increased risk of chromosomal abnormalities in embryos.
