The Claim

After adjusting hand grip strength for fat-free mass, there is no statistically significant difference between non-athlete transgender women (0.6±0.1 kg/kg FFM) and cisgender women (0.7±0.9 kg/kg FFM, p>0.05), indicating that muscle strength relative to lean body mass is comparable between these groups despite differences in absolute strength.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
44score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative
1 study reviewed
In plain English

When you account for how much muscle someone has, trans women and cis women are about equally strong — even if their total strength looks different at first.

What the research says

1 study
  1. Study: Cardiopulmonary capacity and muscle strength in transgender women on long-term gender-affirming hormone therapy: a cross-sectional study

    The study found that when you account for muscle mass, transgender and cisgender women have similar hand strength, which supports the claim.
