Overall satisfaction score [range: 25 – 125]	106.3 (9.0)	96.8 (93.3 – 98.2)	(84.8 – 103.5)

IQR: inter-quartile range.
¹ The mean and standard deviation of the PSI scores of the current study.
² Since there are no benchmark values of the PSI scores, an empirical approach has been adopted to generate reference ranges for the mean PSI subscale and overall scores. All the studies published in English during the period 1 Aug 2003 to 31 July 2013 and reporting PSI scores have been extracted through Google Scholar. A total of seven studies with 14 cohorts’ PSI scores reported were identified, please see the reference list [18–24].
³ The median (inter-quartile range) and range of the extracted studies’ reported mean PSI scores of the 14 cohorts are listed for reference.
