A detailed questionnaire (survey form) made available on https://www.biospectrumindia.com/ (both MNC and Indian players) in this space to capture the needed information for the analysis. This was done during September 10, 2025 to October 10, 2025. Companies shared information with us to the extent it was possible by them. We have collected information about listed companies from stock exchange and financial agencies and Ministry of Corporate Affairs (MCA) as well.

#The revenues considered for the analysis are of services part of the companies as noted above. In several cases, where revenue figures were not available, estimates were arrived in discussion with industry experts.

#For all the ranking purposes, we have taken the CROs business only into consideration. Wherever 'Revenue is mentioned, it means, sales turnover from CROs. Therefore, revenue wherever mentioned is not necessarily the total sales turnover of the company.
