This corrects the article "Circulating leptin and its correlation with rheumatoid arthritis activity: a meta-analysis" on page 116.
J Rheum Dis 2023;30(2):116-125
We discovered that a word error in the INTRODUCTION section and would like to correct it.
The corrected version should be as follows:
Before:
Leptin has both pro-inflammatory and anti-inflammatory effects, and it can activate the Th1 phenotype of T cells, leading to the production of pro-inflammatory cytokines such as TNF-[Symbol - a] and IL-6.
After:
Leptin has both pro-inflammatory and anti-inflammatory effects, and it can activate the Th1 phenotype of T cells, leading to the production of pro-inflammatory cytokines such as TNF-α and IL-6.
We sincerely apologize for any confusion that we may have caused.
