The authors and organisations producing patient-directed knowledge tools should declare their financial and intellectual conflicts of interests.  This is crucial for maintaining transparency, trust and credibility.  These declarations help ensure that the information provided is unbiased and based solely on the best available evidence, free from external influences. By openly disclosing any financial, personal or professional interests, developers can demonstrate their commitment to integrity and ethical standards.  This transparency is particularly important in patient versions of guidelines where clear, accessible and trustworthy information is essential for empowering patients to make informed decisions.  The declaration of interests helps safeguard the quality and reliability of the guidelines, fostering confidence among patients and professionals.
