Major surgical procedures are performed with increasing frequency in elderly persons, but the impact of age on resource use and outcomes is uncertain. ⋯ Elderly patients had a higher rate of major perioperative complications and mortality after noncardiac surgery and a longer length of stay, but even in patients 80 years of age or older, mortality was low.

Overwhelming evidence now indicates that the quality of reporting of randomized, controlled trials (RCTs) is less than optimal. Recent methodologic analyses indicate that inadequate reporting and design are associated with biased estimates of treatment effects. Such systematic error is seriously damaging to RCTs, which boast the elimination of systematic error as their primary hallmark. ⋯ Several examples of flow diagrams are included. The CONSORT statement, this explanatory and elaboration document, and the associated Web site ( http://www.consort-statement.org ) should be helpful resources to improve reporting of randomized trials. Throughout the text, terms marked with an asterisk are defined at end of text.

To comprehend the results of a randomized, controlled trial (RCT), readers must understand its design, conduct, analysis, and interpretation. That goal can be achieved only through complete transparency from authors. Despite several decades of educational efforts, the reporting of RCTs needs improvement. ⋯ The diagram explicitly includes the number of participants, for each intervention group, that are included in the primary data analysis. Inclusion of these numbers allows the reader to judge whether the authors have performed an intention-to-treat analysis. In sum, the CONSORT statement is intended to improve the reporting of an RCT, enabling readers to understand a trial's conduct and to assess the validity of its results.

Because of radiographic evidence of progressive bone loss and the inability to eliminate synovial proliferation with methotrexate, it became apparent that therapy for rheumatoid arthritis needed further advancement. Methotrexate is not a remission-inducing drug and may have dose-limiting toxicity. In the past 2 years, three new disease-modifying antirheumatic drugs (DMARDs) have been approved: leflunomide, etanercept, and infliximab. ⋯ The ultimate value of combination DMARD therapy with methotrexate will be determined by long-term data on safety, efficacy, and effects on radiographic deterioration of bone. Additional long-term observational data on the incidence of joint arthroplasty and disability will help to place the issue of societal costs in a better perspective. This will allow the value of aggressive treatment to be established with certainty.
