PMID 42307368WHAT IT FOUND
Among 63 resistant hypertensive patients, 96.8% were estimated at risk of chronic kidney disease by the SCORED questionnaire.
Women were more likely than men to be at risk. This screening needs lab confirmation.
Key findings
0196.8% of the 63 resistant hypertensive participants were estimated at risk of developing chronic kidney disease by the SCORED questionnaire.
02Female gender was associated with the higher SCORED risk group (p=0.047).
03The mean age was 66.4 years, and age was not statistically significant between risk groups (p=0.052).

What it does not show
The study was cross-sectional and used a purposive, non-probabilistic sample, so it cannot show cause or effect. Only 63 of 180 registered patients were analysed, and 90 were contacted because many phone numbers were missed, nonexistent, or changed; 23 were lost and 4 had died. SCORED has low specificity and can produce false positives, so a high score needs clinical and laboratory confirmation. The paper reports associations with SCORED risk, not measured kidney function, so it does not confirm chronic kidney disease.

The easy way to misread this
Do not read a SCORED score of 4 or more as a diagnosis of chronic kidney disease. The questionnaire has low specificity and can produce false positives, so clinical and laboratory tests are needed.
