Increased Risk of Pain after Electroconvulsive Therapy among Depressed Patients: a Nationwide Study in Taiwan.
Article in The Psychiatric quarterly, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The risk of pain after electroconvulsive therapy (ECT) among depressed patients is still controversial. We aimed to investigate the risk of pain post-ECT among patients with depression. We investigated patients with depression, based on the data in the National Health Insurance Research Database. A comparison cohort comprising depressed non-ECT patients with at least three psychiatric admissions were matched. A Cox proportional regression model was used to investigate the risk of pain between the ECT and comparison cohorts. The ECT and comparison cohorts consisted of 1246 and 4984 patients, respectively. Compared to the control group patients, the ECT group patients had a significantly increased risk of developing overall pain (aHR = 5.753; 95% CI: 2.405-11.760; P < 0.001). Specifically, the risk of developing headache (aHR = 7.270; 95% CI: 1.226-47.731; P = 0.026) and musculoskeletal pain (MSP; aHR = 5.330; 95% CI: 2.937-11.663; P = 0.001) was significantly higher than in the control group. The sensitivity analysis, which involved checking pain events for each week to the end of the study, also provided significant findings in overall pain (aHR = 13.013, 95% CI: 2.121-94.258, P < 0.001), headache (aHR = 10.995; 95% CI: 1.099-122.601; P = 0.042) and MSP (aHR = 14.210, 95% CI: 2.436-82.898, P = 0.003) within 3 weeks of follow-up. This study suggests that depressed patients who undergo ECT may have an increased risk of developing subsequent pain. Further research is warranted to elucidate whether pain is associated with ECT because several potential confounders existed.
