Postoperative Dynamic of Leptin and Fibroblast Growth Factor 21 in 123 Patients Recovering from Cardiac Surgery.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2022. 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
BACKGROUND Cardiac surgery triggers acute changes in serum leptin and fibroblast growth factor 21 (FGF-21). Considering their pleiotropic role in inflammation and abnormal glucose metabolism, perseverance of their abnormal serum level can have a long-term impact on recovery and end-organ failures. Long-term dynamics after cardiac surgery are unknown. MATERIAL AND METHODS Serum was collected from 123 patients before cardiac surgery (tbaseline) and 24 h (t24h), 7 days (t7d), and 3 months (t3m) later. Also, interleukin 6 (IL-6) and C-reactive protein (CRP) assessed nonspecific inflammatory responses. Neurodegeneration was gauged with serum amyloid ß1-40 and ß1-42. Demographic and clinical information, including disposition at 28 days and t3m from admission, were collected. RESULTS Serum leptin increased at t24h (leptinbaseline=613+747.9 vs leptin24h=768±718.1; P=0.0083) and decreased at t7d (leptin7d=499.5±540.2; P=0.043). FGF-21 levels increased at t24h and t7d. Cytokines normalized by t3m. Presurgical leptin levels were higher in Asians and were the primary determinant of postoperative leptin changes. Leptin levels were most elevated in patients undergoing aortic valve and arch surgery; the perioperative increase was significant only in patients with mitral valve surgery. Leptin and FGF-21 did not correlate with markers of general inflammation (CRP, IL-6), which partially resolved after t3m. Amyloid ß1-42 at t3m correlated with leptin peak at t24h. Low prehospital FGF-21 level correlated with the incidence of perioperative stroke; postoperative FGF-21 correlated with discharge to facility vs home. CONCLUSIONS Leptin and FGF-21 evolve independently from the inflammatory response in the aftermath of cardiac surgery and correlate with cardiac remodeling and neurodegeneration markers.
