Overall: A large synthesis of prospective management studies supports adaptive D-dimer thresholds as a practical way to reduce chest imaging while maintaining very low rates of missed clinically important thromboembolism.

Overall: A strong meta-analysis of randomized trials demonstrates meaningful functional improvement from imaging-selected extended-window thrombolysis, although increased symptomatic hemorrhage and the need for advanced stroke workflows temper the net benefit.

Overall: This large, adjusted multicenter cohort links a simple and accessible fluid choice to lower mortality and other patient-important benefits, but residual confounding and absent absolute effect estimates limit certainty.

Overall: A large, pragmatic randomized trial found no patient-important advantage of balanced crystalloid over saline, providing strong and readily implementable evidence that may reduce preference for either fluid based on kidney outcomes.

Overall: This multicenter randomized trial found a clinically substantial reduction in short-term death, recurrent embolism, or decompensation without higher aggregate bleeding, but open-label assessment, few events, two intracranial hemorrhages, and the need for specialized catheter-based care temper the result.

Overall: A large pragmatic cluster-randomized trial found a clinically substantial reduction in antibiotic exposure without a detected increase in short-term morbidity or mortality, although open phased implementation, European setting, and point-of-care procalcitonin requirements temper immediate US adoption.

Overall: A rigorous randomized trial found that YEARS safely avoided CTPA in 22% of patients with active cancer and suspected pulmonary embolism, but its acute hospital setting limits direct relevance to routine US primary care.

Overall: A large matched cohort links prompt emergency evaluation of severe outpatient hyperkalemia with lower short-term mortality, but residual confounding, unreported absolute effects, and unmeasured referral burdens limit causal and practice-changing certainty.

Overall: A strong multicenter blinded trial found no meaningful benefit and more metabolic adverse effects, supporting discontinuation of routine sodium bicarbonate during in-hospital cardiac arrest.

Overall: This well-conducted prospective diagnostic cohort supports an efficient single-troponin rule-out approach, but it does not directly establish the safety of ED discharge or report the strategy's 30-day clinical outcomes.
