Explanation / Answer

Null Hypothesis:H0 Both types of treatment (Combined and Exercise) are the same

Alternate hypothesis:H1= Both treatments are different

The overall effect shows P value = 0.00001 < 0,05 . The null hypothesis can be rejected . This means that there is a significant difference between the two treatments

The Forest Plot indicates that the mean difference in weight loss due to Combined Program and Exercise only program is 6.29 .For Overall 95% CI for the Mean difference lies between -7.33 and -5.26 which implies that Combined Program will result in significant loss of weight than Exercise Only Program.
