I want to find patients between the ages of 45-54 years old who have a principal diagnosis of symptoms, signs, and ill-defined conditions, and who have a diagnosis in the respiratory system or musculoskeletal and connective tissue categories, with an income level and race information included, and their age group, diagnoses, and demographics are all within the specified ranges.
