a Direct effects on the SCC node. Here, node sizes correspond to direct effect magnitude on SCC, where larger nodes highlight the key influencing factors, such as \({\sigma }_{R}\), pitting corrosion, and pH2S. Red arcs indicate the strongest interdependencies, determined from KL divergence b KL divergence matrix showing the strength of interdependencies between variables, with higher values indicating stronger relationships. This asymmetric matrix denotes the directional dependencies from parent nodes (vertical axis) to child nodes (horizontal axis).
