Notes:

^aComplete diagnostic information: clinical diagnosis, pathological diagnosis assigned in Uganda, and pathological diagnosis assigned in The Netherlands;

^bcombination of variable clinical diagnosis of NHL from Uganda used in Table 2 and “assessment of facial tumor” (“yes” if patient had facial tumor, and “no” otherwise). A patient here is classified as BL if she or he had both a clinical diagnosis of NHL and a facial tumor.

Abbreviations: BL, Burkitt’s lymphoma; NHL, non-Hodgkin lymphoma; NCCC, noncancerous chronic condition; n, number of children.
