What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
1
Cohort Studies
Whether higher CD4 counts predict maintenance of muscle strength over time.
A 4-year cohort of 150 young PLWH aged 25–45, measuring CD4 count and grip strength every 6 months, assessing whether baseline or time-varying CD4 predicts change in grip strength, adjusting for ART and viral load.

Cross-Sectional Studies
In Evidence
Association between current CD4 count and grip strength.
A cross-sectional study of 100 young PLWH aged 20–50, measuring CD4 count and dominant hand grip strength, testing correlation while controlling for age, sex, and BMI.
