The statement attributed to Tony Ren regarding China's growing role in the global drug value chain and the 3-5 year projection is found in web search results referencing him. While multiple sources mention Tony Ren and Macquarie Capital, the specific quote and forecast about China's role are only presented in the context of the search results mentioning him, and no other independent source confirms this exact statement.

The claim that Macquarie Capital and McKinsey group the pharmaceutical value chain into four stages (R&D, clinical trials, manufacturing, commercialization) is supported by multiple web search results mentioning the topic and the entities. However, the evidence provided does not contain a single, direct, authoritative source (like a specific report link from McKinsey or Macquarie) that explicitly states this grouping of four stages. The web search results confirm the general topic but do not provide the specific, cited framework from both named entities.
