Here's a list of useful tools and links to other resources that I love, and therefore recommend you check out.
I used many of these resources to construct the Foundations course, so if you took the course it's not necessary to review them.
It might, nonetheless, be of interest to the dilligent ones amongst you =).
GCR Statistics Research Tools
You can use these online tools to guide your study design process, find the right statistical test and calculate sample sizes
The Equator Network
The gateway to the most important research reporting guidelines
2x2 Contingency Table for Diagnostic Studies
Use this excel sheet to calculate prevalence, PPV, NPV, sensitivity, specificity, accuracy, LR+, LR- and posttest probability
2x2 Contingency Table for Intervention Studies
Use this excel sheet to calculate experimental/control event rates, absolute risk reduction, relative risk, odds ratio, and number needed to treat
That's a claim
Online tool to help think critically about health claims. Brilliantly simple. Be sure to check out the 'about health claims' and 'health interventions' sections.
