Your saliva's oxytocin levels stay pretty much the same from day to day if you're healthy, so scientists think it could be a steady sign of your body's baseline oxytocin — unlike cortisol, which jumps around a lot.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'may serve' and 'suggesting', which indicate possibility rather than certainty, placing it in the probability category. These words imply potential rather than confirmed function.

Target
high intra-individual stability across days in healthy adults, suggesting it may serve as a reliable biomarker of individual baseline oxytocin system activity, unlike cortisol which fluctuates more widely

Choir versus Solo Singing: Effects on Mood, and Salivary Oxytocin and Cortisol Concentrations
The study found that oxytocin levels in saliva stayed pretty much the same from day to day in the same people, while cortisol levels jumped around — which means oxytocin might be a better, more stable sign of your body’s baseline state.
