In May 2004, Health Minister Khaw Boon Wan informed Parliament that the NKF had treated 1,414 patients in 1999 and 1,512 patients in 2003. A letter written to "The Straits Times" in April 2004 by Gerard Chuah, the chairman of its Children's Medical Fund board, had claimed that the NKF had 3,000 patients. Singh pointed out the number had been overstated by about 1,000. Durai said he realised there was a mistake only after the letter had been published, but had not corrected it.
