Why did the authors only look at cemented THA’s? And is this for cemented stems and acetabular components or were hybrid THRs also reviewed. Please clarify. In the latest NJR 2019, cemented THRs only accounted for 32% of all THRs compared to 37% for uncemented and 21% for hybrids. This means this study is representative of only 1/3 patients. Will the authors undertake further work looking at uncemented and hybrid THRs also?

Review: The number of excluded patients were differentiated for uncemented/hybrid/reverse hybrids in figure 1 and 2, where figure 2 also confirms the proportion among those groups in NJR. The exclusion of (reverse) hybrids has now been clarified in the text (line X). As explained on line X, the cemented technique is most commonly used in Sweden. This difference between the derivation and validation cohort was discussed as a limitation on line on line X and we have now expanded this section further. As mentioned in a comment above, the possibilities to undertake any further prediction modeling considering uncemented /hybrid/reverse hybrid cases in Sweden is, unfortunately, very limited, since such data is too scarce.
