Figure 7 is an attrition diagram that depicts the status of documents that Kinetic Concepts Inc. submitted for possible inclusion in the report.

The diagram begins with a box outlining the total submission of 593 documents. Several boxes ensue which are connected by arrows going from top to bottom which follow the submissions as they are being screened for possible inclusion in the report.

In the first frame, we compare KCI's submission to submissions by other interested stakeholders and remove any duplicates. KCI had zero duplicate submissions.

An arrow leads from the 593 Unique Submissions to the Initial Screening Phase where documents may be excluded, used in our Background Section or passed to the next level. In this instance, 178 documents were identified for exclusion. 143 were case reports, abstracts, or poster presentations; 1 was product information; 2 were personal communications; and 32 were other documents not relevant to the report.

One document was identified for inclusion in our Background Section.

The path then follows the 414 full articles remaining. During this phase of screening we do a more extensive screening which is again based on our pre-determined inclusion/exclusion criteria. Go to our Methods Section for additional information on the criteria.

272 articles were excluded during this evaluation phase. 31 were animal studies; four were cost analyses; 9 were duplicate studies; 30 included fewer than five patients; 13 were guidelines; five were homemade devices; 3 were in vitro studies; 141 were narrative reviews; nine did not include relevant outcomes; four were not clinical studies; five did not include a NPWT device; one was not a NPWT study; and seventeen were excluded for Other Reasons which may include "inclusion of healthy subjects", "lack of reporting wound healing outcomes" or "patients treated with dual therapies."

Of the 142 full articles remaining for possible inclusion in the report; 117 were already identified in our literature searches. Of the 25 studies that ultimately met the inclusion criteria but were not identified in the literature searches; two studies were included in Key Question 1, 22 studies were relevant to Key Question 3 and one was included as a systematic review of NPWT. Note: Language has been corrected to reflect screening of meeting abstracts, poster presentations and other documents in addition to abstracts of full articles.
