Table 1 Consolidated standards of reporting trial criteria and level of adherence in herbal traditional Chinese medicine treatment clinical trials
Item | Criterion | Adherence |
Group allocation | Randomization | Often claimed; specifics are rarely reported |
Hypothesis | Prospective formulation | Rarely reported |
Parameter | Primary, secondary outcome | Rarely reported; often inclusion of parameters irrelevant to the initial question |
Patients, Treatment time | Selection, rationale for duration | Mostly given |
Intervention, control | Herbal composition, placebo | Often lacking, even for drugs under consideration |
Blinding | Physician, patient blinding | Often lacking |
Data evaluation | Statistical methods | Often lacking. In a lot of publications the reanalysis is impossible or gives different results |
Data selection | Often only report of criteria which are statistically significant. Rarely report of data being comparable | |
Data presentation | Often no data for range, standard deviation, confidence interval or relative risk presented | |
Often no distinction between “in group“ effects and “between group“ effects | ||
Interpretation | Conclusions | Often overoptimistic. Lack of consideration for results not fitting the initial assumption |
