Based on general mathematical assumptions we give an independent, elementary derivation of a theorem by Brown and Dupont (2018 Talk given by F Brown in 'String Math' (Sendai, June 2018)) which states that tree-level amplitudes of closed and open strings are related through the single-valued map 'sv'. This relation can be traced back to the underlying moduli-space integrals over punctured Riemann surfaces of genus zero. The sphere integrals J in closed-string amplitudes and the disk integrals Z in open-string amplitudes are shown to obey J = sv Z.
