Differences between protocol and review

We originally planned to include participants with LVEF ≥ 40% but changed this to LVEF > 40%, since this is a more frequently used cut‐off in clinical trials.

We originally limited our population to symptomatic heart failure (NYHA class > I) at enrolment; however, this criterion was removed to include people with diagnosis of heart failure in whom symptoms had improved the functional class.

We added a clarification regarding the exclusion of cross‐over trials.

We originally planned to include withdrawals due to adverse events in the 'Summary of findings' table. This was changed because this outcome was frequently reported inconsistently, which limits the applicability of a pooled analysis. Instead, we added hyperkalaemia to the 'Summary of findings' table because this adverse event outcome has relevance for clinical decision making. For the same reason, hyperkalaemia was switched from secondary to primary outcomes and withdrawals due to adverse events was switched from primary to secondary outcomes.

We did not pre specify which scale for quality of life we would focus on in the 'Summary of findings' table. To aid comparisons across the 'Summary of findings' tables we chose to include the Minnsota Living with Heart Failure Questionnaire and not the standardised mean difference across two scales which applied only to MRA versus placebo or no treatment comparison.

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).

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 Downgraded by one level due to unclear selection bias in most studies.

2 Downgraded by one level due to concerns about the smaller study being more precise than the larger study.

3 Downgraded by one level due to large variation in size of effect.

4 Downgraded by two levels due to few events and wide CI.

5 Downgraded by two levels due to very small sample size.

6 Suspected publication bias; this is a patient‐relevant outcome that is not reported in most studies.
