SUPPLEMENTARY INFORMATION: The Agency for Healthcare Research and 
Quality has commissioned the Evidence-based Practice Centers (EPC) 
Programs to complete a review of the evidence for Treatment Strategies 
for Patients with Lower Extremity Chronic Venous Disease (LECVD). The 
EPC Program is dedicated to identifying as many studies as possible 
that are relevant to the questions for each of its reviews. In order to 
do so, we are supplementing the usual manual and electronic database 
searches of the literature by requesting information from the public 
(e.g., details of studies conducted). We are looking for studies that 
report on Treatment Strategies for Patients with Lower Extremity 
Chronic Venous Disease (LECVD), including those that describe adverse 
events. The entire research protocol, including the key questions, is 
also available online at: http://www.AHRQ.gov/sites/default/files/wysiwyg/research/findings/ta/topicrefinement/lecvd_protocol.pdf.
    This notice is to notify the public that the EPC Program would find 
the following information on Treatment Strategies for Patients with 
Lower Extremity Chronic Venous Disease (LECVD) helpful:
    [ballot] A list of completed studies that your organization has 
sponsored for this indication. In the list, please indicate whether 
results are available on ClinicalTrials.gov along with the 
ClinicalTrials.gov trial number.
    [ballot] For completed studies that do not have results on 
ClinicalTrials.gov, please provide a summary, including the following 
elements: study number, study period, design, methodology, indication 
and diagnosis, proper use instructions, inclusion and exclusion 
criteria, primary and secondary outcomes, baseline characteristics, 
number of patients screened/eligible/enrolled/lost to follow-up/
withdrawn/analyzed, effectiveness/efficacy, and safety results.
    [ballot] A list of ongoing studies that your organization has 
sponsored for this indication. In the list, please provide the 
ClinicalTrials.gov trial number or, if the trial is not registered, the 
protocol for the study including a study number, the study period, 
design, methodology, indication and diagnosis, proper use instructions, 
inclusion and exclusion criteria, and primary and secondary outcomes.
    [ballot] Description of whether the above studies constitute all 
Phase II and above clinical trials sponsored by your organization for 
this indication and an index outlining the relevant information in each 
submitted file.
    Your contribution will be very beneficial to the ECP Program. The 
contents of all submissions will be made available to the public upon 
request. Materials submitted must be publicly available or can be made 
public. Materials that are considered confidential; marketing 
materials; study types not included in the review; or information on 
indications not included in the review cannot be used by the EPC 
Program. This is a voluntary request for information, and all costs for 
complying with this request must be borne by the submitter.
    The draft of this review will be posted on AHRQ's EPC Program Web 
site and available for public comment for a period of 4 weeks. If you 
would like to be notified when the draft is posted, please sign up for 
the email list at: https://subscriptions.ahrq.gov/accounts/USAHRQ/subscriber/new?topic_id=USAHRQ_18.
    The systematic review will answer the following questions. This 
information is provided as background. AHRQ is not requesting that the 
public provide answers to these questions. The entire research 
protocol, is available online at: http://www.AHRQ.gov/sites/default/files/wysiwyg/research/findings/ta/topicrefinement/lecvd_protocol.pdf.
    KQ 1: Narrative review of the diagnostic methods and diagnostic 
criteria for all adult patients (symptomatic and asymptomatic) with LE 
varicose veins, LE chronic venous insufficiency/incompetence/reflux, 
and/or LE chronic venous thrombosis/obstruction (including post-
thrombotic syndrome).
    KQ 2: Regarding treatments for all adult patients (symptomatic and 
asymptomatic) with LE varicose veins and/or LE chronic venous 
insufficiency/incompetence/reflux:
    I. What is the comparative effectiveness of exercise, medical 
therapy, weight reduction, mechanical compression therapy, and invasive 
procedures (i.e., surgical and endovascular procedures) on health 
outcomes?
    II. What diagnostic method(s) and criteria were used in each study?
    III. How does the comparative effectiveness of treatment vary by 
patient characteristics, including age, sex, risk factors, 
comorbidities, characteristics of disease, anatomic segment affected, 
and characteristics of the therapy (e.g., exercise intensity, type of 
mechanical compression)?
    IV. What are the comparative safety concerns associated with each 
treatment strategy (e.g., adverse drug reactions, bleeding)? Do the 
safety concerns vary by patient subgroup (age, sex, race, risk factors, 
comorbidities, anatomic segment, or disease severity)?
    KQ 3: Regarding treatments for all adult patients (symptomatic and 
asymptomatic) with LE chronic venous thrombosis/obstruction (including 
post-thrombotic syndrome):
    I. What is the comparative effectiveness of exercise, medical 
therapy, mechanical compression therapy, and invasive procedures (i.e., 
surgical and endovascular procedures) on health outcomes?
