Table 3 Formula of Logistic Regression Models to Predict COMLEX 1

From: Early prediction of the risk of scoring lower than 500 on the COMLEX 1

 

Formula

Multiple logistic regression

Log (Odds) = 37.176 - (0.0507 * MCAT) - (0.00212 * MSK I) - (0.00423 * MCM) + (0.00681 * HEMEI) - (0.00574 * CVI) - (0.00506 * RESP I) + (0.00451 * REN I) - (0.00130 * OPP I) + (0.00121 * PCM I) + (0.00178 * GI I) - (0.00403 * ENDO I) - (0.00528 * NEURO I) + (0.00193 * OPP II) + (0.00739 * PCM II) - (0.0114 * REN II) - (0.00884 * CV II) - (0.00759 * RESP II) - (0.00207 * HEME II) + (0.000838 * GI II) - (0.00555 * OPP III) - (0.00690 * PCM III)

Backward logistic regression

Log (Odds) = 32.4857 - 0.00759 (CV I) - 0.0128 (CV II) - 0.00781(RESP II) - 0.0132 (REN II)

Logistic regression of average scores

Log (Odds) = 35.5518 - 0.0442 (average score in all courses)
