Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In patients with coronary artery disease, serum thymosin β4 levels were higher in the good collateral group than in the poor collateral group.

    In plain wordsIn people with coronary artery disease, the body's own thymosin beta‑4 was higher in those with well-developed collateral vessels.

    Summary
    Serum thymosin β4 levels were 1024.50 ± 516.92 ng/ml and 1373.00 ± 1082.88 ng/ml for patients in the poor collateral group and the good collateral group, respectively. Serum thymosin β4 levels in the good collateral group were significantly higher than those in the poor collateral group (P<0.01).

    A total of 190 consecutive patients who underwent coronary angiography were divided into two groups according to coronary angiograms and collateral formation

    In patients with coronary artery disease, serum thymosin β4 levels were independently associated with the collateral Cohen-Rentrop score after adjustment.

    In plain wordsIn people with coronary artery disease, higher natural thymosin beta‑4 levels were linked to better collateral vessel development after adjustment.

    Summary
    After adjustment in the multiple ordinal logistic regression model, serum thymosin β4 levels showed a strong independent association with the collateral Cohen-Rentrop score (χ(2)=4.45, odds ratio=1.00, 95% confidence interval: 1.000-1.002, P=0.035).
