Results became marginally significant (in the direction opposite to our hypothesis) when this model was run without covariates in the model, ( b [SE] = -0.012 [0.007], 95% CI [-0.02 – 0.00], p = .078), and when excluding individuals reporting illness symptoms at either timepoint, ( b [SE] = -0.013 [0.007], 95% CI [-0.03 – 0.00], p = .062). 3.1.1 Exploratory biological analyses Across the full sample, telomere length increased from baseline, and a one-sample t -test on the change scores suggested this finding was marginal, t (222) = 1.77, p = .08.
