Metric used Method of analysis Emission factor (% of applied N) CI_L % CI_U%
Arithmetic mean (AM) Reference data 0.34 0.25 0.44
Geometric mean uncorrected (GMuncorr) Data transformed (y = ln(X)) GM without adjustment for bias 0.18 0.13 0.24
Geometric mean corrected (GMcorr) Data transformed (y = ln(X)) GM with adjustment for bias 0.39 0.29 0.52

Abbreviation: CI_L – 95% confidence interval lower limit; CI_U – confidence interval upper limit.
