1 · What the graph read from it

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.

2 · The registry

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

Aim: Avoidance is a key maintaining factor in major depressive disorder (MDD); however, longitudinal evidence remains limited, and its association with personality traits is not fully understood. This study aimed to (1) examine the longitudinal associations among avoidance, depressive symptoms, and rumination and (2) explore the relationship between avoidance and personality traits in outpatients with MDD. Methods: In this 10-month prospective study, 53 adult outpatients diagnosed with MDD were assessed while receiving routine outpatient psychiatric care. Avoidance, depressive symptoms, and rumination were measured at baseline and follow-up using the Cognitive Behavioral Avoidance Scale (CBAS), 17-item GRID-Hamilton Depression Rating Scale (GRID-HAMD-17), and Ruminative Responses Scale (RRS), respectively. Personality traits were assessed at baseline using the Temperament and Personality Questionnaire (T&P). Patients were dichotomized into an Avoidance Improvement (AI) group (≥9-point reduction in CBAS scores) or a Non-Avoidance Improvement (NON-AI) group based on a median split. Univariate and multivariate regression analyses were conducted to identify factors associated with Avoidance Improvement. Results: The AI group demonstrated greater reductions in depressive symptoms ( Conclusion: Reductions in depressive symptoms and lower Personal Reserve may contribute to decreased avoidance in MDD. These findings highlight the importance of targeting depressive symptoms not only for direct relief but also to disrupt maladaptive avoidance cycles.
