Multisim vs LTspice : Different Result
You have a voltmeter connected to the node in question, but only in Multisim. 

The voltage difference is actually rather inconsequential in practice because it's like two leakage currents fighting. Even 1 or 2 G\$\Omega\$ input impedance on the virtual meter could cause that amount of voltage difference. 

Check the voltmeter’s "internal resistance" parameter in the dialog box.
