Diagnostic value of serum human chorionic gonadotropin and uterine artery Doppler indices in missed abortion.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo evaluate the combined diagnostic value of serum human chorionic gonadotropin (HCG) levels and uterine artery Doppler indices - including pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV), and end-diastolic velocity (EDV) - for identifying missed abortion.
methodsThis retrospective cohort study included 160 patients diagnosed with missed abortion and 200 women with normal pregnancies between January 2019 and December 2023. Serum HCG levels were measured using electrochemical immunoassay, and uterine artery Doppler indices were obtained by transvaginal ultrasound. Statistical analyses included independent t-tests, Pearson correlation, receiver operating characteristic (ROC) curve analysis, and Akaike information criterion (AIC)-based model selection to assess diagnostic performance.
resultsCompared to normal pregnancies, patients with missed abortion had significantly lower HCG levels and significantly higher PI, RI, and EDV values (all P < 0.001). Serum HCG levels were negatively correlated with PI (r = -0.33), RI (r = -0.24), PDV (r = -0.25), and EDV (r = -0.26). The combined diagnostic model incorporating HCG, PI, RI, PSV, and EDV demonstrated the highest diagnostic accuracy, with an area under the curve (AUC) of 0.941 (95% CI: 0.918-0.964), sensitivity of 86.25%, and specificity of 87.00%.
conclusionCombining serum HCG levels with uterine artery Doppler indices markedly enhanced the diagnostic accuracy for missed abortion compared to single biomarkers. This multimodal approach offers high sensitivity and specificity, and may be useful in clinical practice.
