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

Treatment studies of major depression commonly focus on symptoms rather than changes in psychological risk factors. This pilot study examines the relationship between changes in eight defenses specifically related to depression, called depressive defenses, and depressive symptoms. Thirty adults with acute, recurrent major depression were given antidepressant medications (ADM) and randomized to up to 18 months of either cognitive behavioral therapy (CBT), dynamic, or supportive psychotherapy and followed for 4.5 years. Defenses were assessed using the observer-rated Defense Mechanism Rating Scales (DMRS) at intake and 18 months. The Hamilton Rating Scale for Depression-17 item version (HRSD-17) and the Beck Depression Inventory-2nd version (BDI-II) assessed depression periodically. Depressive symptoms decreased significantly on both the HRSD-17 (effect size [ES]=-1.03) and BDI (ES=-1.90). Overall defensive functioning (ODF) increased significantly (ES=.85), improving in 76% of participants. Similarly, the mean proportion of depressive defenses decreased significantly by termination (ES=-.62), although the overall mean remained above that generally seen in healthy adults. Twenty-four percent of participants attained this threshold at termination. After controlling for initial levels, at termination depressive defenses correlated significantly with HRSD-17 (rs=.44, p=.02), and BDI (rs=.33, p=.095). Although causal relationships were not established, depressive defenses were consistently related to changes in depressive symptoms, suggesting that they are promising mediators of treatment effects for major depression. Clinically, defenses are readily identifiable and can serve as important foci in treatment. Finally, levels of depressive defenses that exceed healthy norms may reflect a continuing level of risk for current or future depressive symptoms or episodes.
