O Proton Pump Inhibitors increases the risk of osteoporosis

I have made a search for Protonand Osteoporosis using Pubmed . Several publications suggest that their is a link and some rules out this link . I need to be able to put together a meta-analysis and reach a conclusion whether there is a link or not from these studies depending on its strength.
Basically reaching a conclusion drawn out from all the results of these papers .

I can attach these papers which I found . I dont need more than 10-15 papers for this .
This Thesis is intended for a Rheumatology Diploma
Recent research evidence is suggesting a relationship between the use of PPI(proton pump inhibitors) and osteoporosis causing increased risk of fractures.
