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

purposeTo investigate the interchangeability of mixed and central venous-arterial carbon dioxide differences and the relation between the central difference (pCO₂ gap) and cardiac index (CI). We also investigated the value of the pCO₂ gap in outcome prediction.

methodsWe performed a post hoc analysis of a well-defined population of 53 patients with severe sepsis or septic shock. Mixed and central venous pCO₂ were determined earlier at a 6 h interval (T = 0 to T = 4) during the first 24 h after intensive care unit (ICU) admittance. The population was divided into two groups based on pCO₂ gap (cut off value 0.8 kPa).

resultsThe mixed pCO₂ difference underestimated the central pCO₂ difference by a mean bias of 0.03 ± 0.32 kPa (95 % limits of agreement: -0.62-0.58 kPa). We observed a weak relation between pCO₂ gap and CI. The in hospital mortality rate was 21 % (6/29) for the low gap group and 29 % (7/24) for the high gap group; the odds ratio was 1.6 (95 % CI 0.5-5.5), p = 0.53. At T = 4 the odds ratio was 5.3 (95 % CI 0.9-30.7); p = 0.08.

conclusionsFrom a practical perspective, the clinical utility of central venous pCO₂ values is of potential interest in determining the venous-arterial pCO₂ difference. The likelihood of a bad outcome seems to be enhanced when a high pCO₂ gap persists after 24 h of therapy.
