IGF1 and carpal tunnel syndrome: We identified significant associations between plasma concentrations of IGF-1 and trigger finger (hazard ratio [HR] per 1 SD 1·04 [95% CI 1·01–1·07]; p=0·02) and carpal tunnel syndrome (HR per 1 SD 1·04 [1·02–1·05]; p=4·23 × 10−6), which was concordant with another carpal tunnel syndrome-specific analysis in UK Biobank.32
