Repeated measures of the summative pain scores.

<p>Mean and 95% confidence interval of the summative pain scores are depicted at three time points. Vertical axis: summative pain score, horizontal axis: pre-operative (time = 0), immediately post-operative (time = 1), and post-operative 3-month of interval (time = 3).</p

The conceptual structure of the HERQL.

<p>Circles: latent factors, rectangles: measured variables (questionnaire items). Q01: pain at rest, Q02: hernia protrusion, Q03: pain from mild activity, Q04: pain from moderate activity, Q05: pain from heavy activity, Q08: analgesic usage, Q09: activity restriction, Q11: hernia’s impact on health, Q12: economic burden, Q13: quality of life/global health. Arrows indicate the direction of regressive relationships. Numeric values are regression weights. *P<0.05, **P<0.01.</p

Distributions of the HERQL scores with Likert’s type scales in the field study (n = 386).

The conceptual structure of the extended model of the HERQL with the auxiliary post-operative patient satisfaction module.

<p>Circles: latent factors, rectangles: measured variables (questionnaire items). Q01-05, Q08-09, and Q11-13 are the same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0183138#pone.0183138.g001" target="_blank">Fig 1</a>. Q15: foreign body sensation, Q17: complication severity, Q18: overall satisfaction, Q19: confidence in hernia repair, Q20: quality of life improvement by hernia repair. Arrows indicate the direction of regressive relationships. Numeric values are regression weights. *P<0.05, **P<0.01.</p
