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

backgroundDespite donor organ shortage, many grafts are still discarded due to questionable quality. Functional evaluation of the graft prior to transplantation is compromised by the fact that many kidneys suffer from transient filtration failure early after preservation. We tried to circumvent this problem by using a non-invasive quantitative method to determine metabolic turnover of 13C-acetate in the isolated perfused kidney and then correlating this to graft function after actual transplantation.

methodsFemale porcine kidneys subjected to varying degrees of ischemic injury were put on a machine perfusion device. After injection of non-radioactive 13C-labelled acetate to the perfusate, its turnover by the citrate cycle was quantified by direct detection of 13CO2 in the gas outflow of the oxygenator with a mobile, high precision laser spectrometer.

resultsEven in the absence of urine production the method discriminates all kidneys that go on to resume function from those that do not resume function after actual transplantation. There is no overlap between the two groups.

conclusionsPotentially the 13 C turnover test offers an objective, quantitative and valuable adjunct in the toolbox for pre-transplant evaluation of questionable grafts.
