Table 5 Application of standardized rules for choice of final outcome to estimate effect of breastfeeding on the reduction of pneumonia mortality

From: Breastfeeding for reducing the risk of pneumonia morbidity and mortality in children under two: a systematic literature review and meta-analysis

  Outcome Measures Application of Standard Rules
0-5 months*   
Pneumonia Mortality n=2; 50 events
The risk of pneumonia mortality is 1.66 (0.53-5.23) for predominant BF; 2.50 (1.03-6.04) for partial BF; 14.97 (0.67-332.74) for not BF compared to EBF
Rule 2: Apply effect estimates
6-23 months   
Pneumonia Mortality n=2; 28 events
The risk of pneumonia mortality is 1.92 (0.79-4.68) for not BF compared to any BF
RULE 0: Insufficient Evidence
  1. *Evaluating events for studies where reference category is EBF
