IL-8 and IL-1RA serum levels predicting depression treatment response in 6-week follow-up.
Article in Acta neuropsychiatrica, 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
objectiveThis study aims to ascertain the effect of baseline IL-1Ra and IL-8 in the treatment response of patients with major depressive disorder (MDD) and to clarify the relationship between inflammation markers and depression.
methodsWe recruited 242 patients with a Beck Depression Inventory (BDI) score ≥ 17 referred to secondary care in Finland. The patients’ serum IL-1Ra and IL-8 concentrations were measured at baseline. Montgomery-Åsberg Depression Rating Scale (MADRS) tests and Alcohol Use Disorders Identification Tests (AUDIT) were administered at baseline and six weeks. The antidepressant treatments varied: somewere started, others changed or continued their previous medication, and others had their doses adjusted. Patients started behavioral activation therapy. Linear regression was used with a relative MADRS score change during six weeks as the dependent variable and patient age, AUDIT score, BMI, daily number of cigarettes smoked, sex, and serum IL-1Ra and IL-8 concentrations as independent variables.
resultsHigher baseline serum IL-1Ra and IL-8 levels were associated with a smaller relative change in the MADRS-score within the first six weeks of treatment in linear regression analysis (
conclusionHigher baseline IL-1Ra and IL-8 concentrations were associated with a lesser relative response to depression treatment, particularly in patients with mild depression. Results on IL-8 concur with earlier findings, whereas the association between higher IL-1Ra serum concentrations reduced treatment response is a novel finding.
