Read the article · The Guardian ↗74 studies; 2,584,766 participants in the all-cause mortality analysis.
Adults in prospective cohorts; populations and lifestyle definitions varied.
Healthiest versus least-healthy combinations of smoking, activity, diet, weight and alcohol factors.
Observational association, with residual confounding and heterogeneous lifestyle scores. Not the effect of changing an average person’s habits. Alcohol in the score is not a recommendation to drink.

Read the article · The Guardian ↗Umbrella review of meta-analyses; equivalent hazard ratio for leisure-time physical activity.
Adults in the self-reported leisure-time physical activity syntheses.
Higher versus lower self-reported leisure-time physical activity; contrasts vary across studies.
Authors classify the association as suggestive evidence. Self-report, residual confounding and overlapping reviews limit interpretation. Replaces the combined lifestyle estimate rather than stacking on it.

Read the article · The Guardian ↗CTT individual participant meta-analysis of 26 trials; about 170,000 participants overall.
Participants enrolled in randomized LDL-lowering trials, with varied cardiovascular risk.
Per 1 mmol/L lower LDL cholesterol, across statin versus control and more- versus less-intensive regimens.
Mortality rate ratio is treated as a proportional hazard multiplier in this model. Trial populations and LDL changes differ; not a longevity estimate for healthy people or a prescribing recommendation.

Read the article · The Guardian ↗10 randomized trials; 71,351 participants.
People with type 2 diabetes in large cardiovascular and kidney outcome trials.
Long-acting GLP-1 receptor agonist versus placebo, on top of trial background care.
Class-level synthesis in type 2 diabetes; not transferable to healthy adults, every agent, or lifelong use. Trials already include other care, so combining effects can double-count benefit.

Read the article · BBC News ↗Systematic review of 14 randomized trials; all-cause mortality is a secondary endpoint.
People with chronic kidney disease, with or without type 2 diabetes.
SGLT2 inhibitor plus standard therapy versus placebo or standard therapy.
The 14 trials cover the review as a whole, not necessarily this endpoint. Kidney disease populations differ from the reference life table. Background treatment overlaps with other selections.
