Low Alanine Aminotransferase Blood Activity, a Biomarker of Sarcopenia and Frailty, is Associated With Worse Post-Total Laryngectomy Clinical Outcomes. A Retrospective Analysis of 427 Patients.
Article in Clinical otolaryngology : official journal of ENT-UK ; official journal of Netherlands Society for Oto-Rhino-Laryngology & Cervico-Facial Surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionSarcopenia and frailty status have been shown to be associated with cancer patients' survival. Low alanine aminotransferase (ALT) blood activity was previously shown to be associated with frailty and poor clinical outcomes in cancer patients. This association was not addressed in head and neck cancer patients.
objectivesThis was a retrospective study, investigating the possible association between pre-operative low ALT blood levels and clinical outcomes in patients undergoing total laryngectomy due to malignancy. PATIENTS AND
methodsWe did a retrospective analysis using the largest national Israeli HMO (Clalit health maintenance organization) database, including the demographic, clinical background, laboratory and clinical outcomes of head and neck cancer patients who underwent total laryngectomy.
resultsA total of 427 patients were included. Patients were divided into two groups according to their ALT values: low ALT (0-10 IU/L, N = 100) and normal ALT (11-40 IU/L, N = 327). Low ALT levels were associated with significantly longer duration of in-hospital stay (26 ± 17 vs. 23 ± 16 days, respectively; p < 0.001), higher probability of 1-month, post-discharge unplanned visits to the emergency department (RR = 1.66; p < 0.05) and worse 1-year survival rate (67% vs. 77%, respectively; p < 0.05).
conclusionsLow, pre-operative ALT levels are associated with worse prognosis for total laryngectomy patients. ALT levels may be used for better, personalised medicine by surgeons.
