Table 4.

GEE models for effects of self-reported general fatigue, motivational fatigue, and positive affectivity in association with high effort choices in survivors. Interactions with task-related variables were not significant for general fatigue (p-values > 0.006) therefore not included in model 1. Associations significant at p ≤ 0.006 are depicted bold.
