1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundAmbroxol has a very high affinity for lung tissues; its concentration is approximately 20 times higher in the lung than in the serum. We aimed to evaluate the effectiveness of high-dose ambroxol (990 mg/day) in the improvement of oxygenation and prevention of postoperative respiratory complications in the patients with acute cervical spinal cord injury (CSCI).

methodsA total of 61 acute CSCI patients admitted to the Intensive Care Unit (ICU) of our hospital between January 2009 and June 2011 were included in the study. They were graded as ASIA A and ASIA B according to the classification of the American Spinal Injury Association (ASIA) and were randomly divided into two groups: one group received intravenous ambroxol at 990 mg/day for 5 consecutive days after operation; the other group treated without ambroxol served as control. The results of arterial blood gas analysis on postoperative day 3 and 5 and occurrence of pulmonary complications within 5 days after operation were evaluated.

resultsThe group treated with high-dose ambroxol showed a lower rate of postoperative pneumonia and hypoxemia within 5 days after operation. On the 3rd and 5th days, the oxygenation index in the high-dose ambroxol group (291.02 ± 34.96 and 301.28 ± 37.69) was significantly higher than in the control group (230.08 ± 26.25 and 253.82 ± 26.26), with significant differences between the two groups (P = 0.045 and 0.041).

conclusionAdministration of high-dose ambroxol should be considered as an alternative and effective approach to reduce the postoperative respiratory complications and improve the oxygenation status in acute CSCI patients.
