| Outcomes | Anticipated absolute effects* (95% CI) | Relative effect (95% CI) | № of participants (studies) | Certainty of the evidence (GRADE) | Comments | |
| Risk with usual care | Risk with work‐directed counselling | |||||
| Days until return to work | The mean time to return to work was 7.52 days lower (20.07 lower to 5.03 higher) | ‐ | 618 (4 RCTs) | ⊕⊕⊝⊝ Low1,2 | Work‐directed counselling may result in little to no difference in days until return to work | |
| Adverse effects: cardiac deaths Follow‐up mean: 6 months | 2 per 100 | 2 per 100 (0 to 8) | RR 1.00 (0.19 to 5.39) | 388 (2 RCTs) | ⊕⊕⊕⊝ Moderate3 | Work‐directed counselling probably results little or no difference in cardiac death rates |
| *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; RCT: randomised controlled trial; RR: risk 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. | ||||||
1Downgraded one level due to substantial heterogeneity that we could not completely explain. 2Downgraded one level due to imprecision (two of the four studies did not report the standard deviation). 3Downgraded one level due to imprecision (pooled confidence interval is wide and includes either a possible harm or benefit).
