It was the same (1.7 IIRC) between road and MTB up to 9 speed, except for some old Dura-Ace. When Shimano went 10 speed they had to make it smaller for MTB (a.k.a. Dyna-Sys), and they kept the old ratio for the road 10 speed. Then they changed it for the road 11 speed, and that pull ratio was ported back to the road 10 speed ("new" Tiagra 4700); apparently the old pull ratio was too high for 10 speed, especially with the hidden cables.
So anything Shimano (road/MTB) up to 9 speed has the same pull ratio, as well as the "old" road 10s (up to and including Tiagra 4600 series or 105 5700 series -- but those will not have SGS cage, only GS). I also ran 105 5701 RD with the mentioned 3500 Sora shifter, and it worked great.
