Clinical and sociodemographic characteristics associated with relapse following electroconvulsive therapy for bipolar disorder.

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
objectivesElectroconvulsive therapy (ECT) is an effective treatment for bipolar disorder, but relapse following a successful ECT series is common. We aimed to identify clinical and sociodemographic characteristics associated with the risk of relapse following ECT in bipolar disorder.
methodsUsing data from nationwide Danish registers, we identified all patients receiving their first ECT series with an indication diagnosis of bipolar disorder between 2006 and 2018. We then followed these patients for relapse, defined as either psychiatric admission or a new ECT series, for 6 months following ECT. Associations between clinical and sociodemographic characteristics and relapse were examined via multivariable Cox proportional-hazards regression, yielding adjusted hazard rate ratios (aHRR).
resultsOf the 1473 patients receiving ECT for bipolar disorder (62% females, mean age = 53 years), 34% met the relapse criterion. The following characteristics were associated with an elevated risk of relapse; age <40 (aHRR = 1.54, 95% CI = 1.05-2.26); being a pensioner (aHRR = 1.73, 95% CI = 1.29-2.32), indication diagnosis for ECT being psychotic mania (aHRR = 1.63, 95% CI = 1.16-2.28), psychotic bipolar depression (aHRR = 1.37, 95% CI = 1.06-1.80), mixed episode (aHRR = 1.51, 95% CI = 1.13-2.02), or other bipolar episodes (aHRR = 1.68, 95% CI = 1.28-2.21); and treatment with antipsychotics prior to the course of ECT (aHRR = 1.32, 95% CI = 1.04-1.67).
conclusionPatients with bipolar disorder face a particularly high risk of relapse following ECT if they present with the following characteristics when initiating ECT: age <40, being a pensioner, having received treatment with an antipsychotic before initiating ECT, or having psychotic bipolar depression, psychotic mania, mixed episodes, or other bipolar episodes as the indication for ECT. These findings may guide relapse monitoring following ECT in bipolar disorder.
