Quality of life survey
QoL was estimated using the QoL Short Form Survey (SF-12). The SF-12 is
derived from the SF-36 Short Form survey by scoring the responses of the
mental and physical components of the study. The physical SF-12
component (PCS) investigates physical functioning, pain, and physical
role, while the cognitive component (MCS) summarizes mental health and
social and emotional functioning. The results of these two components
were scored 0-100 by scoring the standard answers to standard questions,
where higher scores represented better mental and physical health.
