From "Gluten-Free Diet and Quality of Life in Patients with Screen-Detected Celiac Disease", May/June 2002. 105-113.
Figure 2. Psychological General Well-Being (PGWB) scores in patients with celiac disease before and 1 year after starting a gluten-free diet. The square dot line represents the change of mean total PGWB score in the symptom-detected group (n = 21). The dashed line corresponds to the change in mean total PGWB score in the group of screen-detected patients (n = 19). The solid black lines in the screen-detected group represent the 5 persons with mild symptoms. The blue line represents the change of mean total PGWB score of 14 asymptomatic patients (patients with mild symptoms were excluded from this analysis). The shaded horizontal area shows the 95% CIs for PGWB scores among a cross-sectional sample of 105 adults without celiac disease. Higher scores represent better quality of life.>
