Table 3 Logistic regression analysis of overall classification and estrogen receptor (ER)-positive classification results on the traditional clinical variable and time to metastasis

From: Long non-coding RNA expression profiles predict metastasis in lymph node-negative breast cancer independently of traditional prognostic markers

Overall classification Metastatic patients (n = 82) Non-metastatic patients (n = 82)
Odds ratio a P a Odds ratio a P a
Age (≤50 versus >50 years) 1.004 0.97 0.914 0.57
Tumor size (range 6 mm to 50 mm) 1.002 0.56 0.990 0.19
Grade (range 1 to 3) 1.057 0.33 0.971 0.75
ER status (negative versus positive) 1.002 0.98 1.095 0.56
Time to metastasis (range 0 to 181 months) 1.001 0.41 - -
ER-positive classification Metastatic patients (n = 55) Non-metastatic patients (n = 55)
Odds ratio a P a Odds ratio a P a
Age (≤50 versus >50 years) 1.088 0.49 0.526 0.053
