  1. In the table appear the samples that coincide in the same diagnosis with that obtained by SnM-PCR. It compares SnM-PCR with microcopy and SnM-PCR with RDT. No samples lacked a diagnosis or were positive without a determination of species. No sample matched P. ovale or P. vivax. Mic microscopy
  2. Italic values indicate significance of P-value (≤ 005)
