Two reviewers (MT and PB) independently, and in duplicate scanned all titles and abstracts and excluded articles that clearly were not RCTs or observational studies of ICS in patients with asthma.
Two investigators (DP, EM) working independently, in duplicate, scanned all abstracts and obtained the full-text reports of records, that indicated or suggested that the study was a randomized trial evaluating antifungal therapy on the outcomes of interest.
Two investigators (AA, EM) working independently, in duplicate, scanned all abstracts and obtained the full-text reports of records, that indicated or suggested that the study met inclusion criteria for the outcomes of interest.
The correlations between duplicate scans ranged from 0.886 to 0.998 and were similar between software versions.
For the estimation of precision, duplicate scans obtained on the same day for nine women were analyzed using both versions of the software.
All 32 scans except one were shown twice, in random order, without informing the observers of duplicate scan viewing, making a total of 63 scan assessments.
Duplicate scans were performed in eight patients demonstrating satisfactory reproducibility.
Moreover, accuracy of BMD and BMC final measurements were determined by duplicate scans of femurs.
Cardiac electron-beam computed tomography scanning was performed using an Imatron C-150XP scanner with 3-mm slices; duplicate scans were performed within 2 min. The Agatston method was used to determine CAC scores and recorded them as the average of the two scans.
In contrast, there were absolute increases in the frequency of duplicate CT scans after PACS of 0.0% (P = 0.92), 0.5% (P = 0.01), and 0.5% (P = 0.01), respectively.
