Figure 4

Values of PPIX-fluorescence in normal findings, findings ≤ mild dysplasia and findings ≥ moderate dysplasia plotted against the time between 5-ALA application and spectroscopy. Fitted curves are normal distributions on a logarithmic time scale. 19* patients/33 biopsies/86 spectra, * insufficient spectra in 3 patients. Arrows represent the SEM of the maxima of the adopted curves in time and value.
