A randomized placebo-controlled trial in healthy volunteers examining the effects of acetaminophen and NO-acetaminophen NCX 701 in human endotoxemia.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
The development of nitric oxide-donating antiphlogistics is intended to improve the tolerability of the parent compounds. The aim of the present study was to explore the potency and tolerability of nitric oxide-donating acetaminophen (NCX 701) in healthy volunteers and to test the hypothesis that NCX 701 could have additional anti-inflammatory efficacy in an experimental model of low-grade human endotoxemia. In this prospective, double-blind, placebo-controlled trial with parallel group design 40 healthy male volunteers were randomized to single oral treatment with NCX 701 (1-2 g), acetaminophen (1 g paracetamol) or placebo before lipopolysaccharide (2ng/kg) infusion. NCX 701 dose-dependently increased plasma and urine nitric oxide concentrations. Pooled analysis of both NCX 701 doses showed a significant, but obviously clinically irrelevant lowering effect on systolic and diastolic blood pressure during the first 5 h. Overall, peak levels of tumor necrosis factor-alpha correlated well with interleukin-6, interleukin-8, monocyte chemoattractant protein-1 and von Willebrand Factor release across all cohorts. There was no major difference between NCX 701 and acetaminophen with respect to their effect on the lipopolysaccharide-induced secretion of inflammation and endothelium activation markers. Overall, a total of 61 adverse events were reported in all treatment arms, mainly related to lipopolysaccharide. Both acetaminophen and NCX 701 effectively reduced the proportion of subjects experiencing headache. Despite substantial nitric oxide release by NCX 701, which reduced arterial blood pressure, nitric oxide did not result in relevant inhibition of lipopolysaccharide-induced inflammation.ISRCTN registry number: ISTCTN-13,358,268.
