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

objectiveTo assess whether suicidal behavior during mixed states exceeds that expected from the manic or depressive components alone.

methodsThis study included 429 participants with bipolar disorder from the National Institute of Mental Health Collaborative Depression Study (CDS). Mood and suicidal behavior were captured using the Longitudinal Interval Follow-up Evaluation and the Schedule of Affective Disorders and Schizophrenia. Suicidal behavior during each mood state, relative to euthymia, was analyzed using Cox regression to allow for repeated events, with a frailty term to account for intra-participant correlation. Mixed states were modeled as a depression-by-mania interaction.

resultsIndividuals with a history of mixed states were at higher risk of suicidal behavior and spent more time depressed, compared to subjects with no such history. In bipolar I disorder, risk increased during episodes of mania (hazard ratio [HR]: 1.96, 95% confidence interval [CI]: 1.28-2.99, P = .0019) and depression (HR: 5.49, 95% CI: 4.01-7.51, P < .0001) and there was a less than additive effect of mixed states. In bipolar II disorder, risk was increased during episodes of depression (HR: 3.66, 95% CI: 2.51-5.35, P < .0001) and there was no excess risk during mixed states beyond that attributable to the depressed component. Most of the excess risk (71%) among those with a history of mixed states was attributable to a depression predominant course of illness.

conclusionsIndividuals with mixed states are at high risk of suicidal behavior, largely due to more time spent depressed. Clinicians should aggressively treat depression to mitigate suicide risk for patients with or without mixed states.
