Personality functioning in bipolar 1 disorder and borderline personality disorder.
Article in BMC psychiatry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
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
backgroundDifferentiation of borderline personality disorder (BPD) and bipolar I disorder (BD) has been challenging. The assessment of shared symptoms in the context of the overall personality functioning, the patient's sense of self, and the quality of his object (interpersonal) relations is proposed to be valuable for the differential diagnosis of these disorders.
methodsWe empirically investigated the level of personality organization (PO), identity integration, and quality of object relations in patients suffering from BD or BPD using the Structured Interview of Personality Organization (STIPO) and the Level of Personality Functioning Scale (LPFS) in 34 BPD and 28 BD patients as well as 27 healthy control persons. Group comparisons and a logistic regression model were calculated to analyze group differences.
resultsThe BPD group showed significantly greater impairment in several domains of personality functioning, namely "identity", and "self- and other-directed aggression", while showing lower impairment in "moral values". The overall level of PO in the BPD group was significantly lower when excluding not only BPD but any personality disorder (PD) in the BD sample. Severity of impaired personality structure had a major impact on symptom load independent of the main diagnosis BD or BPD.
conclusionsOur data show greater impairment in personality functioning in BPD than in BD patients. BD patients present with varying levels of PO, whereas in BPD severe deficits in PO are pathognomonic. The level of PO has a significant impact on symptom severity in both BD and BPD patients. Therefore, careful assessment of PO should be considered for differential diagnosis and adequate treatment planning.
