The Effect of Pulse Width on Subjective Memory Impairment and Remission Rate 6 Months After Electroconvulsive Therapy.
Article in The journal of ECT, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectivesThe aim of this study was to compare the 0.5-millisecond pulse width with broader brief width stimulus and ultrabrief pulse width stimulus in respect to rates of subjective memory impairment and remission 6 months after completion of electroconvulsive therapy (ECT).
methodsThis study used data from the Swedish National Quality Register for ECT. Inclusion criteria were bipolar or unipolar depression with or without psychosis, ECT with unilateral electrode placement, and data on the Montgomery-Åsberg Depression Rating Scale-Self-Assessment and the memory item of the Comprehensive Psychopathological Rating Scale (CPRS-M) before and 6 months after ECT. The primary outcomes were the distributions of patients with a maximum of 10 on the Montgomery-Åsberg Depression Rating Scale-Self-Assessment (remission) and a minimum of 2-step worsening in CPRS-M score according to the ECT pulse widths of <0.5, 0.5, and >0.5 millisecond.
resultThis study included 312 patients. The distributions of patients with remission or a minimum of 2-step worsening on the CPRS-M 6 months after completion of ECT showed no significant differences between the 3 pulse width groups. Older age was associated with a significantly higher rate of remission 6 months after ECT.
conclusionsIn this cohort of patients, no support was found for the previous research finding of lower rates of subjective memory disturbances 6 months after ultrabrief pulse width ECT in comparison with brief pulse width ECT. Older age was associated with higher remission rate 6 months after ECT. Large randomized studies are required to exclude the possibility of long-term differential effects between pulse widths.
