Subgroup Analysis of Outcomes According to NFB
Batteries and magnets were significantly more hazardous than all other
NFB. Epistaxis and nasal discharge were significantly more common in
children who inserted batteries and magnets than other NFB (OR= 14.3 and
10.4 for epistaxis and discharge, respectively, compared to other NFB).
The risk for nasal discharge was significantly higher in non-organic
than in organic NFB (OR=1.86, p=0.02).
