*Rated using the modified Newcastle-Ottawa Scale for case series from Haffar et al.21
†Results not pooled with others due to overlap with cohort from Persa et al.12
‡Results not pooled with others as study cohort was primarily composed of recurrent PDS referred from other institutions.
§Results not pooled with others as study examines a subset cohort from Miller et al8 of pseudovascular PDS.
¶Results not pooled with others as study examined metastatic PDS only.
