  lr.results,
  lr.result_date

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')));

7. System displays procedures linked to the medical record.

SELECT
  pr.procedure_type,
  pr.description
FROM medical_record_procedures mrp

WHERE mrp.record_id = (
SELECT record_id 
FROM medical_records 
WHERE patient_id = (
SELECT patient_id 
FROM patients 
WHERE user_id = (
SELECT user_id
