Summary of findings 12. Teaching: Video‐based learning versus traditional lecture.
| Video‐based learning compared to traditional lecture for preventing highly infectious diseases due to exposure to contaminated body fluids in healthcare staff | ||||||

| Skills in PPE donning assessed with: Assessment scale Scale from: 0 to 100%; Higher is better | The mean skills in PPE donning was 47.4 Percent | MD 30.7 percent higher (20.14 higher to 41.26 higher) | ‐ | 26 (1 RCT) | ⊕⊝⊝⊝ VERY LOW 1 2 3 | |
| *The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval; RR: Risk ratio; OR: Odds ratio; | ||||||
| GRADE Working Group grades of evidence High certainty: We are very confident that the true effect lies close to that of the estimate of the effect Moderate certainty: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different Low certainty: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect Very low certainty: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect | ||||||
1 The randomisation and allocation procedures were unclear and so we downgraded with one level because of study limitations.
2 This is a simulation study so we downgraded with one level because of indirectness.
3 One study with only 26 participants and so we downgraded with one level because of imprecision.
