Таблица доказательств
Evidence tables provide easily navigated layers of evidence in the context of specific clinical questions, using GRADE and a BMJ Best Practice Effectiveness rating. Follow the links at the bottom of the table, which go to the related evidence score in the main topic text, providing additional context for the clinical question.

Эта таблица представляет собой итоговый анализ, представленный в руководстве (подкрепленный систематическим обзором), которое фокусируется на обозначенном выше важном клиническом вопросе.
Confidence in the evidence is very low or low where GRADE has been performed and the intervention may be less effective or likely to be more harmful than the comparison for key outcomes. However, this is uncertain and new evidence could change this in the future.
Население: People with chronic cough and normal chest x-ray and physical examination
Вмешательство: Chest CT scan

Рекомендации, изложенные в исходном руководстве We suggest that clinicians do not routinely perform a chest CT scan in patients with chronic cough who have a normal chest radiograph and physical examination.
Примечание ᵃ The content of this table is based on four observational studies. One prospective study found that the diagnostic yield of chest CT scan was 3/46 (6.5%) participants, while three retrospective studies produced the following results: 20/34 (58%) participants, 9/21 (43%) participants, and 21/59 (36%) participants. The guideline task force noted that the variation in the above results, regarding the diagnostic yield of CT scan, were unlikely to explain the cause of coughs or influence treatment. The guideline task force also noted that there is concern about the potential cancer risk from CT radiation exposure, particularly in children and women, which should be weighed against any diagnostic yields.
