Error in Table. In the article by Jelliffe-Pawlowski et al titled "Risk of Mental Retardation Among Children Born With Birth Defects," published in the June issue of the ARCHIVES (2003;157:545-550), Table 4 data for severe mental retardation (MR) combined (isolated severe MR and severe MR co-occurring with another disability) were included in the "Severe MR and Other Disability" column, and data for severe MR plus other disability were included in the "Isolated Severe MR" column. Table 4 is reprinted correctly here.
