OK.I'll check this problem as soon as possible

Hi,i check the file with Acrobat Reader Pro ,and in this paragraph source code ,there is no spaces.So you see like missing spaces.

Well, that's really odd because if I open the PDF in Preview on Mac OSX and select the paragraph and copy and paste it, all the spaces are present:

Of eleven studies included, six were randomised controlled trials, three were controlled clinical trials, and two were cohort studies. The discharge planning strategies used varied widely, most were limited to preparation of discharge during in-patient treatment. Pooled risk

I'm not sure why there is this difference?

Hi
This spaces problem cause by diffrent font mechanism in MacOS and Windows.If you see the source code of this file,you will see ,there is no spaces.So,this is common in many PDF files.
