Alpha-Fetoprotein as a Biomarker in Pregnancy: From Genetic Disorders to Obstetric Complications.
Review in Current issues in molecular biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Alpha-fetoprotein (AFP) is a glycoprotein primarily produced by the fetal liver and yolk sac during development. It is a multifaceted biomarker with significant applications in the prenatal screening of congenital abnormalities, cancer, and other disorders. The level of AFP in maternal blood may indicate several obstetric concerns and complications during pregnancy. Atypical AFP levels are commonly utilized as a biomarker for detecting fetal anomalies, placental complications, and other pregnancy-related issues. These findings raise concerns regarding the effectiveness of screening maternal serum alpha-fetoprotein (MS-AFP) as a primary indicator of pregnancy problems and underscore the need for further investigation into the functional role of AFP throughout pregnancy. The measurement of MS-AFP has been utilized for the past four decades. It is anticipated that MS-AFP measurement will continue to be utilized as a component of integrated or sequential tests for chromosomal abnormalities and may serve as a prognostic indicator for adverse obstetric outcomes. Critically, whether AFP functions solely as a passive marker or plays active biological roles in pregnancy physiology and pathology remains unresolved, necessitating additional mechanistic investigation and discourse. This review consolidates critical data from numerous studies on AFP, focusing specifically on its diagnostic and prognostic applications for congenital abnormalities and problems during pregnancy. This review also identifies key research gaps regarding the functional biology of AFP, particularly whether AFP functions as a passive biomarker or an active participant in the pathophysiology of adverse pregnancy outcomes.
