WWI: a novel lens on kidney stone risk prediction.

This letter is a comment on an article published in the World Journal of Urology that explores the relationship between weight-adjusted waist circumference index (WWI) and kidney stone risk. The authors of the comment praise the original article for its thorough research and precise statistical analysis. They highlight that the study used a large sample size and employed multivariate logistic regression models, enhancing the scientific nature of the research. The comment also mentions that the original study revealed a non-linear correlation between WWI and the prevalence of kidney stones, providing a more refined reference for assessing kidney stone risk in obese populations. However, the authors note that the predictive effect of WWI on kidney stone risk may still need improvement from a clinical perspective. They suggest that future studies could explore the combined application of WWI with other biochemical parameters to enhance predictive efficacy. Overall, the comment acknowledges the limitations of the original study but recognizes its contribution to understanding the relationship between obesity and kidney stones and offers novel strategies for prevention.
