  • A rapid response is a moderated but not peer reviewed online response to a published article in a BMJ journal; it will not receive a DOI and will not be indexed unless it is also republished as a Letter, Correspondence or as other content. Find out more about rapid responses.
  • We intend to post all responses which are approved by the Editor, within 14 days (BMJ Journals) or 24 hours (The BMJ), however timeframes cannot be guaranteed. Responses must comply with our requirements and should contribute substantially to the topic, but it is at our absolute discretion whether we publish a response, and we reserve the right to edit or remove responses before and after publication and also republish some or all in other BMJ publications, including third party local editions in other countries and languages

    Dear Editor,

    We read with interest the article by Kulkarni et al. [1], which highlights the advances in EKG pattern-recognition to help screen and identify patients with early-stage chronic diseases, particularly type 2 Diabetes (T2D).

    While we recognize the rationale behind the inclusion criteria of the DISFIN study, the included population has a high insulin resistance-diabetes prevalence. However, it is important to note that the participants have a uniformly low A1c value and the time of exposure to hyperglycemia and treatment regimens are unknown. [1] These two variables are essential to consider since both have been described to have a direct relationship with micro and macrovascular complications that could impact EKG features and, thus, the performance of this model. [2]

    Kulkarni et al. [1] do not clarify time since diagnosis of pre-diabetes or T2D and what treatment regimen each patient is undergoing. We ponder if patient classification based on the time of diagnosis, level of hyperglycemia and treatment regimen could help us better understand the onset and biological mechanisms behind EKG feature changes that help better identify subjects with hyperglycemia in all of its spectrum from pre-diabetes to T2D.

    When choosing the ML technique, we noticed that the authors used a K-Fold Cross-Validation scenario for the six candidates. In our opinion, this may result in inconsistencies and skewness on the “K” folds of subsets of the dataset,...
