Elemental analysis shows calcium and phosphorus levels decrease from the bone part to the muscle part of the gel model.
Scientific Claim
EDS analysis confirms a gradient of calcium and phosphorus decreasing from bone to muscle sections in a hydrogel model with hydroxyapatite gradients.
Original Statement
“Regions of Ca and P were observed using EDS mapping. Looking at the percentage of Ca and P present in the sections [...] it can be observed that the abundance of these elements decreases from the bones to the muscles, following the expected trend.”

appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The study directly used EDS to measure elemental distribution, so the gradient observation is factual.
