JOIN lab_results lr ON mrlr.result_id = lr.result_id
JOIN lab_tests lt ON lr.test_id = lt.test_id
WHERE mrlr.record_id = (SELECT record_id FROM medical_records WHERE patient_id = (SELECT patient_id FROM patients WHERE user_id = (SELECT user_id FROM users WHERE username = 'maja.veljanova')));

6. System retrieves the procedures linked to the medical record.

  pmr.duration
FROM prescription_medical_record pmr
JOIN prescriptions p ON pmr.prescription_id = p.prescription_id
WHERE pmr.record_id = (
SELECT record_id 
FROM medical_records

(SELECT patient_id 
FROM patients 
WHERE user_id = 
(SELECT user_id
