Increasing demand for energy requires large-scale construction of power plants and adequate growth of the transmission network. Currently, several high-voltage transmission subsystems (110, 220, 400, 500, and 750 kV) coexist in the same network. We investigate the mechanism of substitution of...

The paper discusses the impact of centre selection on the generalisability of randomised controlled trial (RCT)‐based economic evaluations and suggests a future research agenda. The first section briefly reviews the current methods for addressing generalisability. We argue that these methods...
