Odds ratios for correctly classifying and treating pneumonia in enhanced compared to standard feedback hospitals. At each time point (months 1 to 9), we estimated the odds of correct classification and treatment for patients admitted during the immediately preceding one-month period that coincided with dissemination of the monthly enhanced feedback reports in the intervention arm. The odds ratios (95% CI) are then plotted at these monthly time points and show the predicted odds of correct classification and treatment of pneumonia admissions in the enhanced feedback trial arm compared to the standard feedback arm (adjusted for patient and hospital level factors)
