  2. a This table presents results from the reduced model, which only included variables with multivariable p-values < 0.10. The full model, which included all variables with a univariate p-value < 0.15, also included health facility type (hospital versus health center), health worker supervised on AL use in the past 6 months, and health worker's age. In the full model, none of these factors had statistically significant associations with malaria testing (p-values ranged from 0.12 to 0.99). Both the full and reduced models were based on analyses of 129 patients because of missing values of predictors. The r-squared value for the full and reduced models were 94.9% and 94.4%, respectively.
  3. b In this analysis, all the patients needed testing by either microscopy or a rapid diagnostic test.
