Exploring serum miR-33b as a novel diagnostic marker for hypercholesterolemia and obesity: insights from a pilot case-control study.
Article in BMC endocrine disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Obesity and atherosclerosis are significant metabolic diseases characterized by disrupted lipid metabolism. MicroRNAs (miRNAs) are small, conserved, non-coding RNA sequences consisting of approximately 22 nucleotides, playing crucial roles in biological and pathological functions. Among these, miR-33a/b is particularly associated with metabolic diseases, notably obesity and atherosclerosis. In this pilot case-control study, 45 subjects were examined, and serum miR-33b levels were measured in three groups: a control group, hypercholesterolemic (HC) subjects without obesity (HC group), and obese subjects without hypercholesterolemia (obese group). Serum miR-33b levels were determined using the real-time PCR method. The expression of miR-33b was significantly higher in the HC and obese groups compared to the control group (p < 0.001). The Body mass index (BMI) in the obese group was significantly higher than in the control and HC groups (p < 0.001). Additionally, serum total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-c) levels were higher in the HC group compared to both the control and obese groups. Our study demonstrated a correlation between serum miR-33b levels and HC and obesity. Finally, the ROC analysis demonstrated that miR-33b had an AUC of 0.74 for identifying hypercholesterolemia and an AUC of 0.76 for identifying obesity, indicating its acceptable diagnostic value alongside traditional markers. Therefore, serum miR-33b levels can be considered as a potential biomarker for obesity and hypercholesterolemia, but these finding are preliminary and further investigation is necessary in larger samples to confirm these associations.
