None of the deaths during the trial was attributable to visceral leishmaniasis.
Although the PILLAR and ASPIRE studies enrolled patients who potentially experienced some fatigue at baseline as a result of cHCV infection, much of the fatigue observed in these trials was attributable to side effects of treatment.
Investigations found that all deaths were attributable to HIV disease and were not associated with participation in the trial.
Scientists examining the results of 29 trials involving more than 80,000 people found that only a small minority of side effects were attributable to statins.
Laboratory anomalies were attributable to comorbidities.
RESULTS: No identified lesions were attributable to the interventions.
Therefore, the favourable survival rates in our trial may be attributable to patient selection.
Measuring fidelity improves the internal validity of a study: information on fidelity to the intervention can help estimate the degree to which trial outcomes are attributable to the intervention itself, rather than to other, unknown factors [ 1– 7].
The lack of reported adverse events during clinical trials could be attributable to the short duration of patient exposure to the treatment.
Less impressive results for CTC in two other multi-institutional screening trials may be attributable to inadequate reader training and other study design differences.
