QM rules out non-thermal effects. Once you retreat to thermal effects you have conceded that a cell phone is vastly less dangerous than turning the thermostat from 74 to 75 (if you want to think about extended exposure) or blow drying one's balls (if you want to think about acute exposure). Now those things probably do have some measurable effect - certainly temperature effects sperm count, which is why men are advised not to wear tighty whities. Computing the size of cell phone effects, relative to things like moving from NY to slightly warmer DC is just a simple thermodynamic calculation. If the study is concerned about such tiny relative risks, they are both a) wildly underpowered to detect them and b) certainly aren't making that clear in the abstract. Now, it's possible that our physics-based priors are wildly wrong. But as the calculation I did notes, this study is too underpowered to significantly change our views on that.
