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

backgroundNoradrenaline is currently the first-line vasopressor in treatment of circulatory failure. Its dose reflects illness severity, and together with dopamine, dobutamine and adrenaline, it is used in the Sequential Organ Failure Assessment (SOFA) score to grade cardiovascular dysfunction. Over the years, noradrenaline use has increased and it has largely replaced dopamine. As part of the SOFA-2 update, we conducted a systematic review and dose-response meta-analysis to assess the association between noradrenaline dose and mortality.

methodsWe searched MEDLINE, Embase, and Web of Science from 1 January 2013 to 30 October 2024 for studies reporting mortality by noradrenaline dose in critically ill adults. The primary outcome was mortality. We generated pooled relative risks (RR) and assessed linear and non-linear dose-response relationships. Mortality was also analysed by SOFA-2 noradrenaline categories. The study followed PRISMA guidelines and was registered with PROSPERO (CRD42024501533).

resultsNineteen studies, including totally 29,935 patients, were included in the systematic review, and six in the meta-analysis. We observed a consistent increase in mortality: the relative risk escalated by a factor of 1.5 for every 0.1 µg/kg/min increase in peak noradrenaline dose. We did not find inflection points in the dose-mortality curve. In SOFA-2 categories, hospital mortality was 16.5% in the dose category ≤ 0.2 µg/kg/min, 31.9% in the category > 0.2 to 0.4 µg/kg/min, and 40.3% in the category > 0.4 µg/kg/min (p < 0.001).

conclusionsIn critically ill patients, escalating doses of noradrenaline correlate with an exponentially rising relative risk of mortality. This dose-dependent pattern reinforces the role of noradrenaline dose as a marker of cardiovascular failure severity.
