Erratum

There is a typographical error on p. 7 of the article [1], where it states, “…24.0 % (n = 17,175) were categorized as receiving early physical therapy that was also adherent to the recommendation for active treatment, 19.2 % (n = 13,742) received delayed physical therapy that was adherent, 23,993 (33.5 %) received delayed and adherent care, and 16,649 (23.3 %) received physical therapy that was delayed and non-adherent.” As can be seen, reference to the “delayed and adherent” category is mentioned twice.

Based on Table 4, the second reference to “delayed and adherent” care should have read “early and non-adherent” care. The corrected text is as follows:

“…24.0 % (n = 17,175) were categorized as receiving early physical therapy that was also adherent to the recommendation for active treatment, 19.2 % (n = 13,742) received delayed physical therapy that was adherent, 23,993 (33.5 %) received early and non-adherent care, and 16,649 (23.3 %) received physical therapy that was delayed and non-adherent.”

This typographical correction makes the text in the manuscript now consistent with the data in Table 4, which is correct as originally published.
