The Congress gave little guidance to executive branch agencies on terrorism, did not reform them in any significant way to meet the threat, and did not systematically perform robust oversight to identify, address, and attempt to resolve the many problems in national security and domestic agencies that became apparent in the aftermath of 9/11.
As we did not systematically perform echocardiography or evaluation of coronary flow in these patients, more objective assessment of coronary anatomy and myocardial function is not available.
We did not systematically perform the mitral annulus excursion velocity measurements using tissue Doppler, since it was not routinely used in 2005, at the beginning of the study.
However, prior studies did not systematically perform prostate biopsies and thus cannot determine the true prevalence of prostate cancer in this population.
Although we did not systematically perform complete autopsies of the sacrificed animals, we encountered only one case of metastasis in the liver 50 days after tumor transplant, which suggests a low metastatic potential.
However, we did not systematically perform simulations with larger n's, because a large n here results in large numbers of auxiliary variables, which leads to long computational times.
However, as cardiology trainees in Denmark do not systematically keep track of the amount of examinations performed, these self-reported numbers are an estimate and could thus be unreliable.
We did not systematically record ultrasound signs of crystal arthropathies in our patients, but emphasise that such a study should be performed in the future [ 35].
