Quality of life after laparoscopic vs open sphincter-preserving resection for rectal cancer

Figure 2 Longitudinal assessment of changes in quality of life scores over time for various symptom scales/items. A: Fatigue; B: Micturition problems; C: Chemotherapy side effects (only for patients who received chemotherapy); D: Gastrointestinal tract symptoms; E: Weight loss; F: Male sexual problems (only for men who have been sexually active). A higher score indicates a higher degree of symptoms. Error bars indicate the standard error of the mean. The Friedman test was not performed for male sexual problems, as the number of patients changed at different time points. QoL: Quality of life.
