Rethinking depression diagnosis in ovarian cancer: The role of somatic symptoms.
Article in Cancer, 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
backgroundA recent meta-analysis reported that patients with ovarian cancer have a 3-fold increase in the risk of diagnosis of depression compared to the general population. However, the role of disease-related processes in depressive symptoms-particularly at diagnosis versus after treatment-remains unclear. This study aimed to examine the contribution of somatic symptoms to the assessment of depression severity in patients with ovarian cancer, both at diagnosis and 1 year later, compared to healthy controls.
methodsA total of 428 patients with ovarian cancer completed psychosocial assessments at 1-2 weeks before surgical intervention or initiation of neoadjuvant chemotherapy and at a 1-year follow-up visit. A comparison sample from the Midlife in the United States study was included. Item factor analysis was used to examine the functioning of somatic items in a common depression symptom index in both samples.
resultsSomatic items demonstrated differential functioning between groups. Specifically, patients with ovarian cancer were more likely to endorse somatic symptoms at lower levels of depression as compared to healthy aging adults; they additionally required a lower level of depression to endorse somatic items as compared to nonsomatic items. These differences between patients with cancer and healthy aging adults were no longer present at 1 year postdiagnosis.
conclusionsThese findings support the conclusion that somatic symptoms may disproportionately inflate depression scores among patients with ovarian cancer at diagnosis, which may potentially lead to misclassification or overestimation of depression severity. This highlights the need for refined measurement approaches that account for the somatic burden of cancer in assessing depression during active disease.
