Correction of Labeling Errors in PTB 2019

fixed figureIn our new paper, Scientific Integrity and Anti-Doping Regulation at ISLJ we note that “Errors are inevitable in research, and when they are identified, they are corrected.” Lucky us. We now have an opportunity to show how that is done.

A colleague (thank you!) pointed out a few days ago that we had mislabeled a table heading and corresponding figure legend. We quickly confirmed that this was the case and have asked ISLJ to correct the paper as soon as possible. Fortunately, there is no impact on our conclusions. We apologize for the errors.

Here is our letter to ISLJ:

Dear ISLJ (cc: Ross and Erik):

An eagle-eyed colleague caught a few minor errors in our paper that had gone undetected. We are writing to ask that it be corrected as soon as possible. Fortunately, they are not significant for our conclusions.

Two labels in Table 5 and Figure 2 were reversed inadvertently by us during production.
Here are the corrections:

1. In Table 5, BG17 and BHKE18 should change positions.
2. The same it true for Figure 2, which is attached as corrected [RP: at the top of this post].
3. Also, in the bullet points below the figure, please replace the first four bullet points with the following:

  • For 3 of 11 running events, the performance difference between the highest and lowest tertiles decreased from BG17 to BHKE18, including in 1 of 4 of the regulated events;
  • In three events, the performance difference changed from negative (high T slower than low T) to positive (high T faster than low T);
  • In BHKE18, the low T tertile is faster than the high T tertile in 3 of 11 events, compared to 6 of 11 events in BG17.
  • In the four regulated events, the average difference in times was increased by 0.4% in absolute terms (i.e. from 1.6 to 2.0%), and 3 of 4 meets the BHKE18 standard for statistical significance (BG17 reported 1 of 4).

None of these changes alter our analysis or conclusions, as the key point in this section was the magnitude of differences between the two studies, not the relative accuracy of one study over the other. Nonetheless, we regret the errors and apologize.

Please let us know any questions, Thank you,
