Inflammation-associated depression in cholangiocarcinoma: impacts of surgical resection and radiotherapy.
Article in BioPsychoSocial medicine, 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
backgroundCholangiocarcinoma (CCA) is an aggressive malignancy associated with systemic inflammation and a high psychological burden. However, the relationship between inflammation and depression in CCA remains poorly understood. This study aimed to investigate the association between systemic inflammatory markers and depression in patients with CCA.
methodsWe conducted a prospective cohort study of patients aged ≥ 20 years with a diagnosis of cholangiocarcinoma treated at a single tertiary medical center between May 2021 and September 2024. Depression was evaluated using the Patient Health Questionnaire-9. Generalized linear mixed models were applied to examine the relationships between inflammatory markers and depression.
resultsA total of 164 patients with CCA were included, comprising 97 intrahepatic cholangiocarcinoma (ICC) and 67 extrahepatic cholangiocarcinoma (ECC) cases. Depression prevalence was 19.9% at baseline and fluctuated over time, ultimately decreasing to 10.4% at 12 months. In multivariate analyses, not receiving surgical resection and higher C-reactive protein (CRP) levels were independently associated with depression in the overall CCA cohort and in the ICC subgroup. In the ECC subgroup, receipt of radiotherapy and lower albumin levels were independently associated with increased depression risk.
conclusionsOur study reveals a significant association between inflammatory markers and depression in CCA patients, with CRP emerging as a key marker. Notably, surgical intervention was associated with a reduced risk of depression, whereas radiotherapy in ECC patients was associated with an increased risk of depression.
