PPPM healthcare costs by item in patients with and without brain metastases.
All costs were converted into US dollars from the Korean won using the exchange rate of 2019. The statistical significance of the difference between the costs of patients with and without BM was assessed using the t-test. The asterisk (*) indicates p<0.05; PPPM, per patient per month; BM, brain metastases.
