The Effect of Air Pollution on Lung Development from 10 to 18 Years of Age (Original Article, N Engl J Med 2004:351;1057 - 1067) . On page 1059, under the heading Statistical Analysis, in the list of model adjustments, lines 18 through 20 of the left-hand column should have read “the square of log values for height,” rather than “body-mass index (the weight in kilograms divided by the square of the height in meters); the square of the body-mass index,” as printed. Also, in the right-hand column, lines 3 and 4 should have read “ordinal variables for the field technician and the spirometer,” rather than “indicator variables,” as printed. These errors had no bearing on the analysis of persons with clinically low lung function. Adjustment for body-mass index and indicator variables as intended changes the results slightly but does not affect the reported associations between growth and pollution during an eight-year period. The corrected values for Table 2Table 2Mean Levels of Growth in Pulmonary Function during the Eight-Year Study Period, from 1993 to 2001.
