2. Fig 1
Percentages of study participants grouped by gestational age at birth who had at least 1 positive skin prick test reaction. Within the very-low-birth-weight (VLBW) group (gestational age at birth <37 weeks), reduction of gestational age by 1 week was associated with a lower risk of atopy based on skin prick test results (adjusted OR, 0.82; 95% CI, ).

3. Fig 2
Percentages of study participants grouped by gestational age at birth with high concentrations (>0.8 kU/L) of at least 1 serum allergen-specific IgE. Within the very-low-birth-weight (VLBW) group (gestational age at birth <37 weeks), a 1-week reduction in gestational age was associated with a lower risk of high concentrations of allergen-specific IgE (adjusted OR, 0.82; 95% CI, ).
