Differences between protocol and review

  • Types of outcome measures. Primary outcomes. We followed new recommendations from Cochrane, and changed primary outcomes to: all‐cause mortality, liver‐related mortality, and serious adverse events.

  • Types of outcome measures. Secondary outcomes. We followed new recommendations from Cochrane, and changed secondary outcomes to: liver‐related morbidity, health‐related quality of life, and non‐serious adverse events. We moved the other planned secondary outcomes: vitamin D status, bone mineral density, biochemical indices, failure of virological response, and acute cellular rejection in liver transplant recipients under 'Exploratory outcomes'. We added alkaline phosphatase, triglyceride, cholesterol, and calcium to exploratory outcome 'biochemical indices' to be able to analyse the effect of vitamin D supplementation on the broader spectrum of biochemical indices.

  • Data synthesis. We considered a P value of 0.025 or less, two‐tailed, as statistically significant if the required information size was reached due to our three primary outcomes (Jakobsen 2014).

  • Data synthesis. In our Trial Sequential Analysis, the diversity‐adjusted required information size was based on the event proportion in the control group; assumption of a plausible relative risk reduction; a risk of type I error of 2.5%; a risk of type II error of 10%; and the observed diversity of the included trials in the meta‐analysis (Jakobsen 2014; Wetterslev 2017).

  • Marko Bjelakovic joined the team of authors during the preparation of the review and Marija Bjelakovic left the team of authors during the preparation of the review.

Notes

Cochrane Reviews can be expected to have a high percentage of overlap in the methods section because of standardised methods. In addition, overlap may be observed across some of our protocols and reviews as they share at least three common authors.

El uso y la enseñanza del modelo PICO están muy extendidos en el ámbito de la atención sanitaria basada en la evidencia para formular preguntas y estrategias de búsqueda y para caracterizar estudios o metanálisis clínicos. PICO son las siglas en inglés de cuatro posibles componentes de una pregunta de investigación: paciente, población o problema; intervención; comparación; desenlace (outcome).

Para saber más sobre el uso del modelo PICO, puede consultar el Manual Cochrane.

Trial Sequential Analysis on rapid virological response in the two vitamin D trials was performed based on a mortality rate in the control group of 5%, a relative risk reduction (RRR) of 30% in the intervention group, a type I error of 2.5%, and type II error of 10% (90% power). There was no diversity. The required information size was 11958 participants. The cumulative Z‐curve crossed the conventional monitoring boundary for benefit.

*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; RCT: randomised clinical trial; OR: Odds ratio.

GRADE Working Group grades of evidence

  • High quality: this research provides a very good indication of the likely effect; the likelihood that the effect will be substantially different is low.

  • Moderate quality: this research provides a good indication of the likely effect; the likelihood that the effect will be substantially different is moderate.

  • Low quality: this research provides some indication of the likely effect; however, the likelihood that it will be substantially different is high.

  • Very low quality: this research does not provide a reliable indication of the likely effect; the likelihood that the effect will be substantially different is very high.

1 Downgraded one level due to risk of bias: all trials were at high risk of bias.
2 Downgraded one level due to inconsistency of evidence: intertrial heterogeneity was significant.
3 Downgraded one level due to imprecision of evidence: Trial Sequential Analysis of vitamin D trials shows that we had insufficient information.
4 Downgraded one level due to indirectness of evidence: rapid virological response is a surrogate outcome.
5 Downgraded one level due to indirectness of evidence: early virological response is a surrogate outcome.
6 Downgraded one level due to indirectness of evidence: sustained virological response is a surrogate outcome.
7 Downgraded one level due to indirectness of evidence: acute cellular rejection is a surrogate outcome.
