Long-term outcome of patients depending on NGAL expression and intensity in months.

<p>(<b>A</b>) DFS in all patients by NGAL expression neg. vs. pos. (<b>B</b>) DFS in all patients by NGAL intensity 0–1 vs. 2–3. (<b>C</b>) DFS in HR positive patients by NGAL expression neg. vs. pos. (<b>D</b>) DFS in HR positive patients by NGAL intensity 0–1 vs. 2–3. (<b>E</b>) DFS in patients without pCR by NGAL expression neg. vs. pos. (<b>F</b>) OS in patients without pCR by NGAL intensity 0–1 vs. 2–3. NGAL: neutrophil gelatinase-associated lipocalin. DFS: disease-free survival. OS: overall survival. HR: hormone.</p
