2. Figure 1
Mean PSQI and ISI scores and 95% confidence intervals grouped by FD severity. A significant linear trend was identified between FD severity and PSQI and ISI scores (P < .001). Patients with moderate (Mod) and severe FD had higher PSQI and ISI scores than healthy controls and patients with mild FD symptoms (P < .05).

3. Figure 2
Mean SF-12 PCS and MCS component T scores (standardized scores with a mean of 50 and SD of 10) with 95% confidence intervals for healthy volunteers and FD patients grouped by self-reported FD symptom severity as mild, moderate (Mod), and severe. A significant linear trend was identified between FD severity and PCS and MCS scores (P < .001). Lower PCS scores were found in patients with moderate (Mod) and severe FD compared with healthy controls (P < .05). The mean MCS score was significantly lower in patients with severe FD compared with mild FD or healthy controls (P < .05).
