Cross-Sectional Reference Data From 29 European Countries for 6 Frequently Used Depression Measures.
Article in JAMA network open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Importance: Cross-sectional reference values are needed to enable adequate interpretation of individual and group-level scores of frequently used depression measures in research and clinical practice. Objective: To provide age-, sex- and country-specific reference values for the PROMIS depression metric as well as 6 frequently used depression measures. Design, Setting, and Participants: Within the cross-sectional European Health Interview Survey (EHIS) wave 3, depressive symptoms were assessed using Patient Health Questionnaire (PHQ)-8 in a general European population from 2018 to 2020. PHQ-8 data were used to score depression severity on the Patient Reported Outcomes Measurement Information System (PROMIS) depression T-score metric and estimated reference scores for 6 other measures. EHIS wave 3 had response rates ranging from 12% to 78% with 22 countries having a response rate of over 50%. PHQ-8 responses from the general population across 29 European countries were analyzed from March to October 2023. Exposures: Completion of EHIS. Main Outcome and Measure: PROMIS depression T-score estimates. Results: A total of 287 530 participants from the general population (156 655 [54.1%] were female) provided PHQ-8 responses. The median (IQR) PROMIS depression T-score of the overall European population was 45.33 (39.11-51.68), 44.11 (38.06-50.40) for male participants, and 46.37 (40.00-52.76) for female participants. Lowest scores were observed in Serbia with a median (IQR) of 40.81 (35.45-46.59) and highest were observed in Iceland (48.60 [42.60-54.45]). Conclusions and Relevance: In this cross-sectional study of depressive symptom scores in the general population, scores differed by age, sex, and country. Item response theory modeling and quantile regression enabled modeling of depression questionnaire reference data on a common, instrument-independent metric.
