This treatise - Roga Viniscaya - is more popularly known as Madhava Nidana after the name of its author.  It is counted as the first among the Laghu Trayi (the lesser triad) of Ayurvedic literature.  It is considered as the ideal book dealing with Nosology (knowledge of diseases) and has earned a praise for its author as "Madhava is best for Nidana".  It has retained its importance as a text-book on the subject since the last thirteen centuries.  It enjoyed great reputation as an authoritative text not only in India but even in other countries as can be judged by its translation into other languages and many commentaries.
