In the interest of transparency and to avoid potential and actual conflicts of interest, funding disclosures are standard operating procedure in the scientific research community, particularly when the research is expected to undergo peer review. The funding source should not effect the scientific method or statistical analysis of the results, but sometimes it does. For example, there have been several recent studies that have concluded that HCQ is ineffective against the Chinese Wuhan Flu and potentially dangerous. The scientific method for the study and conclusions could very well be sound, but perhaps HCQ was only given to people who were already in critical care as opposed to the first signs of infection. You may ask yourself "why?" only to discover that the study was funded by big pharm, Bill Gates, and George Soros.

Peer review is supposed to establish the research as valid, not the political bias of the scientists.
