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

backgroundPlasma exchange (PLEX) is an effective treatment for antibody-mediated neurological disorders and has been shown to be equally efficacious to intravenous immunoglobulin (IVIg) with comparable adverse event profiles. IVIg has traditionally been the preferred treatment option due to its ease of use. However, advancing technology has allowed PLEX to be performed with a centrifugal system via peripheral access as opposed to central access via a membrane filter.

methodsWe prospectively collected data from a cohort of patients who underwent PLEX at the Wessex Neurological Centre, UK, to perform a cost-minimisation analysis comparing PLEX to IVIg, the standard of care, between May 2019 and May 2020. Data obtained included indication, admission type (inpatient, daycase or intensive care), access (peripheral or central), number of PLEX cycles, exchange volume, patient weight, complications and clinical outcomes. The cost of PLEX delivered in an outpatient setting for an average 80kg person was calculated and compared to the equivalent cost of delivering IVIg by means of a cost-minimization model.

resultsThe provision of PLEX was roughly half as costly when compared to what it would have been for IVIg (£886 per exchange vs £1778 per infusion or £4432 per cycle of 5 exchanges vs £8890 per cycle of 5 infusions). Our cohort included a total of 44 patients who received a total of 357 PLEX exchanges during the 12-month period (the majority of which were in a daycase setting). We calculated an annual cost saving for PLEX over IVIg of £318,589. The robustness of this result was confirmed by a one-way deterministic sensitivity analysis, showing the cost-effectiveness of PLEX.

conclusionOur findings demonstrate that PLEX is more cost-effective than IVIg in this setting. Our study supports the economic case for development of plasma exchange centres in regional neurology units, a case made all the more relevant in the context of constrained supplies of IVIg.
