Off Topic: 10 ways to find medical studies on the web

Ways I use to discover/find medical studies

Henry Lahore, founder of VitaminDWiki - April 2018
I have searched for information all of my life
Before I became an Electronics Engineer I had hought about being a librarian


Have used for decades, has RSS
I often limit a search to having "vitamin D" in the title so as to not get too many returns
28,000,000 studies as of April 2018
Very powerful filters – such as author, word must be in title, human,

Dimensions - started using April 2018

91,000,000 studies, 14,000,000 PDFs as of April 2018
Indexes medical studies from PubMed, Europe, Australia, etc.
Coverage appears to be a superset of PubMed
Usually has a list of references used by the study
Can sort by many attributes
Attention score is nice = how reported the study was in social media, etc
Can filter by sources - for example - Search for Magnesium but filter to only Clinical journals
Results of search for "Vitamin D" Autism

Trip database

TRIP = Turning Reseach Into Practice
Free and PRO ($45/year) versions
Pro version grealty improves searching tools
  Example - searching by word proximity in title, etc,
   This is the only search engine I am aware of that allows searching by word proximity
Search for "Vitamin D" ==> 16,721 results April 2018
Can filter and sort the results in many ways

Google Scholar

HUGE - all kinds of studies - not just medical
I have used it for years, has RSS
Has great links to citations of older papers
More citations = paper was considered of value
After you have found a great paper elsewhere you can follow the citations to see what has happened since

http://sci-hub.tw - Russia - URL changes frequently

"the first pirate website in the world to provide mass and public access to tens of millions of research papers"
64,000,000 PDFs as of May 2018
I only use Sci-Hub to find a free PDF if I already know the PubMed# or DOI #
Gets copies via University subscriptions
PDFs are sometimes accepted manuscripts, not finals
Sci-Hub often not have the PDF on the day it is first published
Sometimes Sci-Hub does not respond at all (perhaps too many visitors from a country)
About 50% of the time Sci-Hub will have previously downloaded the PDF
Sometimes it will get the PDF while you wait - about 2 minutes
Check Check Twitter for URL updates

Sci-Hub article on Verge - Feb 2018

  • "Elsevier, for example, boasts a nearly $35 billion market cap. It has reported a nearly 39 percent profit margin for its scientific publishing arm"
  • Open Access now (not Sci-Hub) now accounts for 28 % Digital Object Identifiers
  • "...many Open Access publishers charge scientists fees — often anywhere from a few hundred dollars up to around two thousand — for processing their articles, whether they’re accepted or not."
  • 70 % of peer-review Open Access models do not charge anything
  • Researchgatews pressured into taking down 7 million unauthorized copies of their (publishers) papers.
  • Sci-Hub has “gained access” to “around 400 universities.”
  • "Now, once users pointed Sci-Hub toward an article, the site would check every university proxy server until it found one through which it could download the paper, and would download it automatically."
  • " “Access from China and Iran was blocked for some time because Sci-Hub couldn’t serve as many requests as were coming from these countries".
  • ".She also made Sci-Hub inaccessible to Americans (except those using VPNs) — in part because of the number of download requests, but also because she wanted to avoid becoming a target for lawsuits.__



Free for the first month, then monthly, yearly subscriptions
You can read (but not download) most PDFs behind paywalls

Clinical Trials in US

Excellent way to get details behind a study - especially when publisher charges from a PDF
Nice way to see what dose sizes and health problems are being tried


Typically 20% of the PDFs will be here a few months after publication

Kopernio add-on to Chrome browser

This is an add-on which activates automatically at some of the above search sites
Provides links to PDF various means: standard and non-standard
Green PDFs appear in PubMed. Google Scholar, Dimensions, etc if a PDF is available for free


Search on any topic using searchbar at top of every page
- - - Non-English searches can be made if you have a Chrome browsers plugin
Browse by health topic with the left column
If you have a study title you can go to seachbar. type "quote" then 30-50 characters of title then end quote
After about 10 second - - -
   First result wil be the PDF itself
   Next result will be the webpage which has the PDF attached
You can subscribe to updates on any of 150+ topics,updates to a web page, etc.


Has in-depth overviews of nutrition and supplements


Wide variety of medical information
I trust about 70% of what they say
