Fluoride levels in Community X were collected for approximately 72% of the complete trial period, while levels at Community Y were reported for approximately 15% of the trial period.
The time from stroke was comparable between groups, but it should be acknowledged that a mean difference over 1 month may be clinically relevant, requiring a stratified analysis according to distance since stroke onset for future reporting of the complete trial.
The most robust results of the NPC Trial come from the recent analyses of the complete trial data for prostate cancer incidence, the diagnosis of which was confirmed by analysis of prostate-specific antigen (PSA) in the plasma (Duffield-Lillico et al, 2003a, 2003b).
The HTKS effect was still significant both for the completed trial number during feature and conjunction foraging (F 1,65) = 5.05 p = 0.028, feature and F 1,65) = 8.25 p = 0.006 conjunction).
This paper systematically examines, for each of the completed trials, the experimental design type chosen and its original rationale, the main findings of the trial, and the strengths and weaknesses of the design in hindsight.
We obtained the full text of result publications for 62.2% (97/156) of the completed trials.
For these participants, only data from the completed trials was included in later analyses.
At the end of each trial, ENS (energy not supplied) for the trial is calculated and EENS (expected ENS) for the completed trials and impact factor on steady-state security due to large wind farms are estimated.
We could not get the email or telephone number of the investigators for the completed Chinese trials in clinicaltrials.gov because contact information is only displayed in that registry when the study is recruiting subjects.
First, manufacturers of antiemetic drugs have more commercial interest in prophylaxis strategies which may be the reason for the complete lack of trials with older classic antiemetics when treatment of established PONV is concerned.
