Occupational status also had a significant effect, with urban manual workers showing higher handgrip strength than the reference group ( p = 0.001), while the association for urban non-manual workers did not reach statistical significance ( p = 0.067).

The sentences
Among performance variables, handgrip strength demonstrated a moderate positive association with muscle-related indices, whereas VO2max exhibited a negative trend with body fat percentage.
Associations with p values below 0.05 but above 0.0033, such as BF% with back strength (r = −0.046, p = 0.026) and SMM with push-up performance (r = 0.056, p = 0.006), were considered nominally significant only and were not interpreted as robust associations. 3.4 Results of multiple linear regression analyses Multiple linear regression analyses were conducted to identify independent predictors of key physical performance outcomes ( Table 4 ).
