We thank the authors for the interest in our article
[1], and for highlighting these points. We agree on the superiority of
tandem mass spectrometry (TMS) over radioimmunoassay for vitamin D
estimation. We could not measure vitamin D using TMS due to logistic
concerns, and this can be considered as a limitation of our study.
R 2 was
maximum in model 3 (afternoon sun index), as also mentioned in text
‘Maximum R2 (0.367) was
achieved in Model 3 when afternoon sun index replaced cumulative sun
index in the model. We regret the printing error in the table where
values of morning and afternoon Sun index got interchanged.
