Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations 

The recruitment period was from Mar 2008 to Oct 2009 when the study was stopped early (Data and Safety Monitoring Board (DSMB) decision based on futility) on Nov 2009. The study participants were recruited from the Infectious Disease Institute, Makerere University, Kampala, Uganda. 
PreAssignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment 

Total of 353 participants were screened; only 73 were randomized and thus 280 were not enrolled: 146 of them did not have cognitive impairment, 55 of them lacked laboratory inclusion criteria, and 79 of them had "others".

No text entered.  
[3]  Other relevant method information, such as adjustments or degrees of freedom: 
The chisquare score was 0.024 and the degree of freedom was 1.  
[4]  Additional information, such as whether or not the pvalue is adjusted for multiple comparisons and the a priori threshold for statistical significance: 
The pvalue is not adjusted for multiple comparisons.

Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data 

The estimated sample size was 100; however, due to early termination of the study, the total number of randomized participants was 73.
