Statistical Consulting

Introduction

Welcome to the Statistical Consulting program of the Department of Radiology Research Support Core. The purpose of this program is to provide accessible statistical services to Radiology faculty, fellows, residents and staff, which include assistance with

  • study and experimental design
  • sample size calculations/power analysis
  • choosing and applying appropriate statistical methodology
  • data analysis
  • interpretation and presentation of results
  • grant and manuscript review
  • other statistical questions.

 

These services may be utilized from the early planning stages of a new study to the preparation of grant proposals to the analysis and presentation of results for publication. In particular, meeting to discuss a new study before any data is collected is recommended, if feasible. This can help identify the most efficient way to collect the data and not miss important variables.

Contacting and Scheduling

You may contact us in two ways:

  1. Submit the online consultation request form for a meeting (teleconference ok)
  2. Email your question directly to radstats@uw.edu

 

Unless you have previously met regarding your present project, it is highly recommended that you first schedule a meeting in order to sufficiently cover the goals and background. This is to ensure the highest quality advice, which depends strongly on context.

Meetings times are generally flexible and are typically available within

  • Monday: 8:00AM - 5:00PM
  • Wednesday: 8:00AM - 5:00PM
  • Thursday: 1:00PM - 5:00PM
  • Friday: 8:00AM - 1:00PM
Actual availability varies week to week, so please confirm your desired meeting time through the online form or email. Unless you have made other arrangements, such as your individual office or a teleconference, the following locations will typically be used for meetings:
  • UWMC - Templeton Library
  • HMC - Radiology library
  • SLU - Any available meeting room
Other arrangements can be accomodated on a case-by-case basis.

Depending on demand, it may be difficult to schedule time or get hands-on assistance on short notice. Therefore, you are strongly encouraged to schedule meetings early, well ahead of deadlines. This will also help identify any obstacles or roadblocks up front when there is enough time to remedy them. Demand may be much higher than usual near common abstract and grant deadlines, so please plan accordingly.

Project Intake

Depending on demand, the degree of hands-on assistance that will be provided will vary. To prioritize requests, deadlines, complexity of analysis, software availability, and skills of the investigator will be taken into account. Again, making requests early is recommended.

Co-Authorship and Acknowledgment

If substantial contributions (e.g., study planning based on statistical estimation, statistical planning, data analysis, etc) were made by the consulting statistician, and if that is acknowledged by the Principal Investigator, the consulting statistician should be entitled to a co-authorship in a publication and will have the commensurate responsibility for the publication as a whole. If the contributions were useful but do not rise to the level of a co-authorship, we simply ask for acknowledgement in the publication.

Sending Data

You may send data to radstats@uw.edu when you are ready to get help analyzing it. Typically an initial meeting is required to explain the project and variables meanings. When you send data, please indicate any confidentiality issues and if the data should be destroyed after a particular time. In addition, please remember to remove any protected health information (PHI) like patient names, addresses, etc.

Feedback

Other questions, comments, and feedback may be directed to Laura Grant at grantl2@uw.edu.
