Linear Regression on PSA Levels

Variable	Coefficient	SE	p Value
Age at diagnosis	−0.286	0.117	0.021
Gleason score	1.089	0.543	0.055
Somatic mutation in tRNA	5.778	2.203	0.014

The outcome variable was the PSA level; the influence of somatic mutations in tRNAs was evaluated by adjusting also for age and Gleason score.
