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.

Abstract

Background: Post-Covid syndrome is a debilitating condition which may be caused and/or aggravated by autoantibodies. The current study aimed to determine whether autoantibody depletion by immunoadsorption is effective to reduce the symptom burden of patients with post-Covid syndrome. Methods: IAMPOCO was a randomised, patient-blinded, sham-controlled crossover trial of immunoadsorption with tryptophan adsorbers versus sham treatment in patients with post-Covid syndrome at a tertiary academic care centre. The primary outcome was the difference in change in symptom severity before and after the respective therapies. Secondary outcomes included treatment safety, prevalence of autoantibodies against G protein-coupled receptors (adrenergic and muscarinergic receptors), and the influence of treatment on autoantibody levels. Findings: 40 patients with post-Covid syndrome and a symptom severity of at least 2 on the Post-Covid-19 Functional Scale were included and randomised to a treatment sequence. There was no difference in change in symptom severity between immunoadsorption and sham; odds ratio in Post-Covid-19 Functional Scale, OR = 1.17 (95% CI, 0.41-3.36; p = 0.771), mean difference in MFI-20 2.4 (95% CI, -3.7-8.5; p = 0.437), in CFS 0.09 (95% CI, -4.5 to 4.7; p = 0.970), in Bell-Scale -2.6 (95% CI, -6.9 to 1.8; p = 0.246), in MoCA score -0.01 (95% CI, -1.2 to 1.1, p = 0.993) and in Handgrip-strength deviation from individual normal value 1.3 (-0.83 to 3.5, p = 0.234). 34 adverse events occurred, 10 during or after sham treatment and 24 during or after immunoadsorption. Autoantibodies against G protein-coupled receptors were depleted by immunoadsorption but not sham treatment. Interpretation: Immunoadsorption was not effective in reducing symptom burden in post-Covid syndrome.
