'The Lancet' reportedly insists on the use of the raised decimal point
(http://www.download.thelancet.com/flatcontentassets/authors/artwork-guidelines.pdf)
and gives the instructions 'Type decimal points midline (ie, 23·4, not
23.4). To create a midline decimal on a PC: hold down ALT key and type
0183 on the number pad, or on a Mac: ALT shift 9.' On Windows, that
gives U+00B7 MIDDLE DOT.
And in this linked-to document it's raised to only what appears to be
half the x-height; I'd raise a multiplicative dot to half the M-height.
Philippe's post just now might relate to that in some way.
