The Claim

Only 8 studies involving 195 participants were available for analysis of load-specific muscle fiber hypertrophy, indicating a limited evidence base for drawing definitive conclusions about fiber type-specific training effects.

What the research says

Supports is higher

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

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

Description
1 study reviewed
In plain English

Scientists looked at only 8 small studies about how different weight training affects muscle growth. They found there isn't enough research yet to say for sure which exercises work best for building specific types of muscle fibers.
