The surname of Sreekanth Arikatla incorrectly appeared as Sreekanth Artikala in original article.
In the Abstract, the values in the Results section were slightly incorrect and should read as follows:
Three questions from the face validity questionnaire were excluded due to lack of response. Ratings to 8 of the remaining 10 questions (80%) averaged above a 3.0 out of 5. Average intracorporeal suturing completion time on the VBLaST-SS© was 425 (standard deviation = 170 s) seconds compared to 410 (178 s) seconds on the box trainer (p = 0.657). Deviation in needle insertion from the black dot was smaller for the box trainer than the virtual simulator (1.69 vs. 7.10, p < 0.001).
In the Results section, there was an incorrect reporting of the total number of medical students included. The first sentence should read as:
Nineteen medical students (MS, n = 19), six residents (n = 6) and a research assistant (n = 1) voluntarily enrolled in this study.
In the Results section on Face Validity, there was a mismatch between the data in the text and that reported in Table 2 for the highest rated question. The third sentence should read as:
Those questions that rated the highest were the usefulness of the VBLaST-SS© simulation in learning hand-eye coordination skills compared to the FLS (3.88) and the degree of realism of the target objects in the VBLaST-SS© compared to the FLS (3.84).
In the Results section on Performance, there were inaccuracies in the reported performance data. The Performance section paragraph should read as:
Performance.
Performance scores are shown in Table 3. Average intracorporeal suturing completion time on the VBLaST-SS© was 425 (standard deviation = 170) seconds compared to 410 (178) seconds on the box trainer (p = 0.657). Deviation in needle insertion from the black dot was smaller for the box trainer than the virtual simulator (1.69 vs. 7.10, p < 0.001).
Table 3.
Comparison of the performance scores between VBLaST-SS© and Real FLS
| VBLaST-SS© | Real FLS | p value | |
|---|---|---|---|
| Completion time (s) (mean ± SD) | 424.64 ± 170.088 | 409.68 ± 178.240 | 0.657 |
| Incision gap (mm) (mean ± SD) | 1.139 ± 0.873 | 0.788 ± 1.238 | 0.064 |
| Deviations to black dots (mm) (mean ± SD) | 7.102 ± 4.944 | 1.694 ± 2.769 | < 0.001 |
Accompanying this, Table 3 was incorrect as appeared, and should appear as:
As a result of the updated p value, the fourth sentence in the Discussion should read as:
However, there was a trend toward significance for remaining incision gap and significant difference in performance quality for remaining incision gap and needle insertion deviation.
