No, the study covered three sweeteners in mice. From the original study (paywalled, accessed via my university):
> To determine the effects of NAS on glucose homeostasis, we added commercial formulations of saccharin, sucralose or aspartame to the drinking water of lean 10-week-old C57Bl/6 mice
They found effects from all three sweeteners, though the strongest effects were from saccharin.
The followup study confirming the effects on humans, which was a much smaller study, only involved saccharin.
