The study assessed how well the Haller index can predict the risk of recurrence in patients with primary spontaneous pneumothorax.
Data from 285 patients (mostly young men) who had undergone CT scans were analyzed over several years, categorizing them into those who experienced recurrence and those who did not.
Results indicated that a higher Haller index was linked to a greater risk of recurrence, suggesting that using this index could help identify high-risk patients for better management strategies.
