The Japanese lead extraction registry (J-LEX): Annual report 2020.
Article in Journal of arrhythmia, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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 Japanese Heart Rhythm Society established a nationwide, mandatory, multi-center, prospective, observational registry of transvenous lead extraction (TLE) named the Japanese lead extraction registry (J-LEX) in 2018. We have published the first annual report of J-LEX with 661 cases from 42 hospitals. The second annual report of J-LEX in 2020 enrolled increased numbers of 785 cases from 75 hospitals. TLE procedure was attempted on patients with an average age of 71.7 years old, male in 72.5% in the hybrid operating room in 57.9%, and in standard OR with a C-arm fluoroscope in 18.7%. The indication of TLE was an infection in 62.8% and the guideline classification was class-I in 67.4% and class-IIa in 23.8%. The average implantation duration of target leads was 7.9 years. Complete removal was achieved in 96.6% of the target leads and clinical success in 98.1% of the patients. Perioperative complications were observed in 7.1% of the patients. One patient died during a TLE operation and the other three patients died in-hospital (cardiac death in one patient and non-cardiac in two patients). Although the annual J-LEX report in 2020 demonstrated an increased number of TLE procedures despite the first pandemic year of coronavirus disease-2019 (COVID-19), perioperative complications increased a little in comparison with J-LEX 2019.
