Recent Perspectives on the Physiological and Therapeutic Benefits of Placental Extracts in Chronic Noninfectious Diseases and Aging.

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
introductionNon-communicable diseases (NCDs), including metabolic disorders, cardiovascular diseases, liver pathologies, and age-related syndromes, are a major global health challenge. Human placental extract (HPE) and related formulations, such as Laennec and porcinederived extracts, have been investigated as cell-free therapeutic agents capable of modulating physiological and immunological pathways.
methodsA systematic literature review was conducted using PubMed, MEDLINE, Scopus, Google Scholar, and the National Library of Medicine databases. Only original English-language research articles were included. Data were extracted on the biochemical composition, mechanisms of action, and therapeutic outcomes of placental extracts in preclinical and clinical studies.
resultsHPE was shown to enhance liver function by reducing oxidative stress, promoting hepatocyte regeneration, and regulating apoptosis and autophagy. In metabolic disorders and cachexia, it preserved muscle and adipose tissue and alleviated symptoms of cirrhosis and metabolic dysfunction- associated steatohepatitis. Laennec and porcine extracts improved iron metabolism, reduced hepatic fibrosis, and enhanced glucose regulation in type 2 diabetes and non-alcoholic fatty liver disease. Additional reported effects included anti-aging properties, relief in chronic fatigue syndrome, and dermatological benefits, such as reduced hair loss and improved allergic contact dermatitis. DISCUSSION: Placental extracts, such as HPE, Laennec, and porcine formulations, show promise for treating NCDs, including metabolic disorders, liver pathologies, and age-related syndromes. Preclinical and clinical studies highlight their mechanisms, which involve reducing oxidative stress, promoting hepatocyte regeneration, regulating apoptosis/autophagy, and improving iron metabolism and glucose control. Benefits include alleviating cirrhosis, type 2 diabetes, cachexia, chronic fatigue, and dermatological issues like hair loss. While the evidence is encouraging, largescale trials are needed to confirm their efficacy and the underlying molecular pathways.
conclusionPlacental extracts exhibited diverse therapeutic effects across multiple NCDs, mediated by immunomodulatory, antioxidative, and metabolic regulatory mechanisms. While current evidence from preclinical and clinical studies is promising, large-scale, rigorously designed trials are needed to validate efficacy and clarify molecular pathways.
