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

objectiveTo investigate a technique using 20% albumin for measurement of plasma volume in critically ill patients. DESIGN AND

settingLaboratory and clinical investigation in the adult intensive care unit and anaesthetic laboratories of a university hospital. PATIENTS: 12 patients fulfilling ACCP/SCCM criteria for septic shock. INTERVENTIONS AND MEASUREMENTS: Each patient received (125)I-labelled albumin, and the volume of distribution was measured at 1 and 10 min. The accepted standard plasma volume measurement (98% of the 10-min volume of distribution) was calculated. Immediately thereafter 200 ml 20% human albumin was given. Albumin concentrations were measured before and 1 min after this 40-g bolus, and the volume of distribution calculated using a formula that corrected for the 200 ml fluid in which the albumin was dissolved.

resultsPlasma volumes measured using the albumin dilution technique at 1 min were smaller than the standard technique by 110+/-280 ml; limits of agreement were from -660 to +440 ml (-16% to +11%). Plasma volumes measured by (125)I-albumin at 1 min were smaller than the standard by 120+/-110 ml; limits of agreement were from -330 to +100 ml (-8 to +2%).

conclusionsNon-labelled albumin can be used easily and quickly to measure a plasma volume in ICU patients and gives a moderately accurate estimate when compared with the (125)I-labelled albumin methods. The normal isotope method over-estimates plasma volumes in septic patients because excessive transcapillary escape of albumin is inadequately compensated for by the standard correction factor.
