Odds ratios of mortality between patients who received antibiotic prophylaxis via the respiratory tract and those who received placebo or no therapy. (a) Primary analysis (only randomized controlled trials); (b) secondary analysis (including non-randomized trials). Vertical line = 'no difference' point in mortality between the two regimens. Horizontal lines = 95% confidence interval. Square = odds ratio; the size of each square denotes the proportion of information given by each trial. Diamond/triangle = pooled odds ratio for all studies.
