Como obter bons resultados de ensaios clínicos
Examples of Methods for Pharmaceutical Companies to Get the Results They Want from Clinical Trials:
Conduct a trial of your drug against a treatment known to be inferior.
Trial your drugs against too low a dose of a competitor drug.
Conduct a trial of your drug against too high a dose of a competitor drug (making your drug seem less toxic).
Conduct trials that are too small to show differences from competitor drugs.
Use multiple endpoints in the trial and select for publication those that give favourable results.
Do multicentre trials and select for publication results from centres that are favourable.
Conduct subgroup analyses and select for publication those that are favourable.
Present results that are most likely to impress - for example, reduction in relative rather than absolute risk.
