For older Chinese women, body mass index and waist size are equally good at predicting multiple health risks, but waist-to-height ratio is slightly less accurate.
Scientific Claim
In elderly Chinese females aged 60 years and older, body mass index and waist circumference have similar predictive ability for three or more metabolic risk factors, with area under the curve values of 0.676 and 0.669, respectively, while waist-to-height ratio has a lower predictive ability (AUC 0.659).
Original Statement
“In females, the AUC of BMI and WC did not differ and were greater than for WHtR, WHpR and BAI. BMI had the strongest predictive ability for both genders. The AUC of BMI and WC did not differ in females, while WHtR had a lower value (0.659).”

Assessment Explanation
The study is observational and reports statistical associations; 'associated with' is appropriate to avoid implying causation while accurately reflecting the data.
More Accurate Statement
“In elderly Chinese females aged 60 years and older, body mass index and waist circumference are associated with similar predictive ability for three or more metabolic risk factors, with area under the curve values of 0.676 and 0.669, respectively, while waist-to-height ratio shows lower predictive ability (AUC 0.659).”
