“…More longitudinal investigations are required to understand the dynamics of financial toxicity during the disease course and its impact on HRQOL. Interestingly, our included studies showed that the correlation strengths between financial toxicity and overall HRQOL were slightly stronger in studies that used English instruments (median = 0.53, range = 0.33-0.73) 57,58,60,62,64,66,73,81 than those in other languages, for example, Mandarin Chinese, Italian, and Arabic (median = 0.43, range = 0.34-0.52), 51,55,67,72,79,80 and conducted in countries with universal health coverage (median = 0.49, range = 0.34-0.73) 55,58,66,72,79,80 than those without (median = 0.42, range = 0.33-0.63). 51,57,60,62,64,67,73,81 Nevertheless, we had inadequate number of studies to further examine (eg, performing subgroup analysis) the potential impact of instrument language or universal health coverage on the association between financial toxicity and HRQOL.…”
