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

purposeEmergence of multidrug-resistant strains in intensive care units has renewed interest in colistin, which often remains the only available antimicrobial agent active against resistant Pseudomonas aeruginosa. The aim of this study is to compare lung tissue deposition and antibacterial efficiency between nebulized and intravenous administration of colistin in piglets with pneumonia caused by P. aeruginosa.

methodsIn ventilated piglets, colistimethate was administered 24 h following bronchial inoculation of Pseudomonas aeruginosa (minimum inhibitory concentration of colistin = 2 microg ml(-1)) either by nebulization (8 mg kg(-1) every 12 h, n = 6) or by intravenous infusion (3.2 mg kg(-1) every 8 h, n = 6). All piglets were killed 49 h after inoculation. Colistin peak lung tissue concentrations and lung bacterial burden were assessed on multiple post mortem subpleural lung specimens.

resultsMedian colistin peak lung concentration following nebulization was 2.8 microg g(-1) (25-75% interquartile range = 0.8-13.7 microg g(-1)). Colistin was undetected in lung tissue following intravenous infusion. In the aerosol group, peak lung tissue concentrations were significantly greater in lung segments with mild pneumonia (median = 10.0 microg g(-1), 25-75% interquartile range = 1.8-16.1 microg g(-1)) than in lung segments with severe pneumonia (median = 1.2 microg g(-1), 25-75% interquartile range = 0.5-3.3 microg g(-1)) (p < 0.01). After 24 h of treatment, 67% of pulmonary segments had bacterial counts <10(2) cfu g(-1) following nebulization and 28% following intravenous administration (p < 0.001). In control animals, 12% of lung segments had bacterial counts <10(2) cfu g(-1) 49 h following bronchial inoculation.

conclusionNebulized colistin provides rapid and efficient bacterial killing in ventilated piglets with inoculation pneumonia caused by Pseudomonas aeruginosa.
