#### **14.1 Pain reduction**

One trial with 40 individuals that produced very low quality data demonstrated a clinically significant advantage of exercise over standard therapy after around three months.

9 studies with 528 people produced very bad quality evidence that at >3 months, there was no clinically significant difference between exercise and conventional treatment. At >3 months, there was no clinically significant difference between exercise and usual care, according to very low quality evidence from 1 study with 95 participants.

#### **14.2 Health related quality of life**

Five studies with 372 participants and very low quality data each shown a clinically significant advantage of exercise over standard therapy after >3 months. One study with 54 participants found very low to low quality evidence that exercise had a clinically significant advantage over standard care after more than three months. Regular care was found to have a clinically significant advantage compared to exercise at about three months in one study with 95 individuals using very low to low quality data. 259 people in 2 studies with very low quality evidence demonstrated a clinically significant advantage of exercise compared to conventional treatment at >3 months. Very low quality evidence from 1 study 95 participants showed no clinically important difference between exercise and usual care at ≤3 months or at >3 months.

#### **14.3 Physical function**

Very low quality data from 2 studies with 155 people and 1 research with 95 participants indicated no clinically relevant difference between exercise and usual care at 3 months and no clinically important difference between exercise and usual care at >3 months, respectively.

Three studies with 169 participants and very low quality data each shown a clinically significant advantage of exercise over standard care after more than three months. Three studies with a total of 246 individuals produced very low quality evidence that exercise had a clinically significant advantage over standard care after more than three months.

#### **14.4 Psychological distress**

One trial with 60 individuals produced low quality evidence that exercise had a clinically significant advantage over standard therapy after about three months. A lack of clinically significant differences between exercise and usual care at >3 months was revealed by low quality data from 3 studies with 123 participants. At >3 months, there was no clinically significant difference between exercise and standard care, according to low quality data from 4 studies with 306 individuals. At >3 months, there was no clinically significant difference between exercise and standard care, according to low quality data from 4 studies with 320 participants. One trial with 50 individuals that had very low quality data found no clinically significant difference between usual treatment and exercise after more than three months. There was no clinically significant difference between exercise and standard treatment after >3 months, according to very low quality data from 1 research with 95 individuals [80].
