Associations Between Cognitive Impairment, Depressive Symptoms, and Work Productivity Loss in Patients With Bipolar Disorder: A Cross-Sectional Analysis.

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
aimTo evaluate the relationship between cognitive impairment and work productivity loss in patients with bipolar disorder.
methodsWe enrolled outpatients with bipolar disorder aged 18-59 years undergoing treatment and actively employed or on sick leave. Baseline demographic, medical resource use, and employment data were collected. We evaluated work productivity, cognitive impairment, quality of life (QOL), depressive symptoms (defined as a Patient Health Questionnaire-9 [PHQ-9] score of ≥ 10), and sleep disturbance. This interim analysis examined correlations among baseline symptom scores and correlations of each symptom score with work productivity loss and QOL.
resultsAmong 211 participants, cognitive impairment was moderately correlated with depressive symptoms (r = 0.595) and insomnia (r = 0.481), and depressive symptoms and insomnia were highly correlated (r = 0.719) (all p < 0.001). Work productivity loss (presenteeism) was moderately correlated with cognitive impairment (r = 0.474), depression (r = 0.577), and insomnia (r = 0.547) (all p < 0.001). Depression had the strongest influence on presenteeism (multiple regression analysis, regression coefficient: 22.98; p < 0.001). Among participants without severe depressive symptoms (PHQ-9 ≤ 19), cognitive impairment (13.91, p = 0.007) and insomnia (13.80, p = 0.016) strongly affected presenteeism. Among participants without moderately severe or severe depressive symptoms (PHQ-9 ≤ 14), insomnia affected presenteeism (23.14, p = 0.011). QOL was moderately negatively associated with cognitive impairment (r = -0.653), depression (r = -0.699), and insomnia (r = -0.559) (all p < 0.001). In multiple regression analysis, cognitive impairment (-0.12, p < 0.001), depression (-0.12, p = 0.010), and insomnia (-0.16, p < 0.001) were significantly associated with QOL.
conclusionsTreatment should focus on improving the core symptoms of bipolar disorder, insomnia, and cognitive impairment.
