The content of the counseling varied between the trials: three studies [ 23 and 24, 25] focused only on dietary counseling, while other studies also included counseling on, for example, exercise and smoking.
In addition, the patterns of utilization associated with clinically diagnosed conditions may differ between the trial and observational study setting, further complicating the task of identifying SREs based on utilization data using approaches employed in RCTs.
In an attempt to understand the disparity between the preclinical and clinical trial studies, it was noted that the lengths of injury in the clinical setting were longer than those of the preclinical studies.
We classified one study as being at high risk of bias due to a discrepancy between the trial registry entry and the published study regarding the specified primary outcomes (Raynor 2007).
Such standardization would allow a better understanding of the difference in rehabilitation intensity between the trial's randomized groups, and between the trial and prior studies [ 12].
The heterogeneity between the trials and groups was studied using the χ test (or Cochran Q statistic) for statistical significance, and measured with I statistic for degree of heterogeneity [ 14, 15].
The method of producing the emulsion was the major difference between the current study and the trial done in healthy adults with malaria antigens in which there were some prolonged local reactions and two cases of erythema nodosum [13].
The mean characteristics of patients at entry to the long term model are shown in table 5 and reflect the mean adjusted differences between the intervention and the control (that is, adjustment was made to eliminate differences at baseline between the two study arms of the trial).
In addition, there are no analysis assessing the correlation between the study type (randomized, controlled trial, observational study, and so forth) and the publication rate.
The discrepancy between the ANITA trial and our study is minimized when the chemotherapy scheme is included in the analysis.
