Currently, I am conducting a meta-analysis on the association between BMI and prognosis. I discovered that the studies used various cut-offs. However, only two studies are eligible for dose-response meta-analysis (DRMA) as only these studies reported >1 cut-off values. Regarding this study:
- Is it possible to perform a dose-response meta-analysis when only 2 studies are included?
- Is there any statistical software that is able to perform dose-response meta-analysis other than STATA and R?
- Regarding the preliminary analysis, we would like to perform a two-class analysis by comparing studies reporting 1 cut-off values (i.e. >=30 vs <30, >=25 vs <25). Can you pool all the cut-offs in the analysis? Or do you have to group the analyses based on the cut-offs?
Any help will be much appreciated. Thank you very much
