Dynamic Changes in Serum Choline Acetyltransferase and Acetylcholinesterase in Septic versus Non-Septic ICU Patients: A Prospective Exploratory Study.
Trial report in Journal of inflammation research, 2026. 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
Objective: To compare serum choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) levels between septic and non-septic critically ill patients, and to evaluate their dynamic changes, associations with inflammatory markers, disease severity, and prognosis in sepsis. Methods: In this prospective observational study, 87 patients with sepsis and 93 non-septic critically ill controls were enrolled. Blood samples were collected from septic patients within 12 hours (T1), 24 hours (T2), 48 hours (T3), and 7 days (T4) after intensive care unit (ICU) admission, while the non-septic group underwent sampling only at T1. Serum levels of ChAT, AChE, and inflammatory cytokines (IL-6, IL-10, TNF-α) were measured. A linear mixed model was used to analyze dynamic changes, repeated measures correlation (rmcorr) to assess associations between variables, receiver operating characteristic curves to evaluate discriminative ability, and multivariable logistic regression to identify independent influencing factors. Results: Septic patients had significantly lower ChAT at T1 than non-septic controls (P<0.001), whereas AChE levels did not differ. Both ChAT and AChE were lower in septic shock than in non-shock septic patients (both P<0.05). Linear mixed‑model analysis revealed a significant overall group effect for AChE, with lower levels in non‑survivors (group effect, P = 0.013); however, no significant intergroup difference was observed at T1 (P = 0.098). ChAT showed moderate discriminative ability for sepsis, with an area under the ROC curve of 0.70, and was identified as an independent factor associated with sepsis in this exploratory cohort (OR = 0.85, 95% CI: 0.76-0.94, P = 0.001). The inverse association between ChAT and sepsis was stronger in patients aged ≥65 years (interaction P=0.023). Conclusion: This exploratory study demonstrates that serum ChAT levels are significantly decreased in septic patients, correlate with disease severity, and show moderate discriminative ability for sepsis. Linear mixed‑model analysis revealed that AChE levels were overall lower in non‑survivors than in survivors, although the prognostic value at individual time points was limited. Age modifies the ChAT-sepsis association, which should be considered in clinical evaluation.
