*+, positive; –, negative; AdV; adenovirus; AdV7, adenovirus type 7; FFPE, formalin-fixed and paraffin-embedded; NA, not available because the specimen sizes were too small for analysis; RT-PCR, reverse transcription PCR; UD, under detection limit.
†Virus genome copy numbers were quantified by using real-time RT-PCR or real-time PCR: 2+, 102–103 copies/μL; 3+, 103–104 copies/μL; 4+, 104–105 copies/μL; 5+, 105–106 copies/μL; 6+, 106–107 copies/μL; 7+, 107–108 copies/μL.
