Group 0 comprises patients who are not doing any reading or who only do sporadic reading. Group 1 comprises patients who are only reading non-challenging material on a regular basis and those who read highly challenging material on a non-regular basis. Group 2 comprises patients who read challenging material on a regular basis at least once a week. Only test results with statistical significance are shown. Significance p < 0.05.
