Following publication of the original article [1], the authors identified some errors in the published equation on Table 2, the published Fig. 3 (the estimated odds and likelihood ratio were incorrect due to our mistake in specifying the equation within the calculator), and the discussion part (related to the figure) in the manuscript. The correction details are stated as follows:

• 1) Log (Log globulin) of the 4^th entry under Formula column should not be superscripted.

Table 2 Multivariable fractional polynomial logistic regression model for diagnostic prediction of multiple myeloma. (imputed dataset with a total n = 586)

• 2) Our previous equation embedded within the online web calculator was incorrect. After correction, the model estimated the predicted odds of MM at 0.436 with a positive likelihood ratio of 1.429 (suspected MM) (Fig. 3). Figure 3 was corrected accordingly. The suggestion in the following sentence was also corrected to follow the model’s estimates. The 9^th and 10^th sentence of the 3^rd paragraph on page 9 should read:

The model predicted the odds of MM at 0.436 with a positive likelihood ratio of 1.429 (suspected MM) (Fig. 3). Based on that, this patient should have been considered for referral to a hematologist for further work-up and a definitive diagnosis.
