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

Background: Spinal cord stimulation (SCS) devices are routinely trialed to assess pain and functional improvement before permanent lead implantation. Lead migration is a common complication that may cause a loss of therapeutic effect in patients who may otherwise benefit from SCS. The timing of lead migration during the trial period is currently unknown. Objectives: We hypothesize that significant lead migration may occur early in the SCS trial period, such as postoperative day 1 or 2, which may allow for contact stimulation adjustment to prevent false negative trial results. As such, in this study, we aim to evaluate the incidence and distance of lead migration in early thoracic SCS trial period. Methods: We performed a case series of 27 patients ≥19 years of age who received differential target multiplexed thoracic SCS trials for chronic neuropathic pain from July 1, 2020 to July 1, 2023. Patients with a neuropathic pain diagnosis failing medical treatment, without structural pathology limiting epidural access, and with psychiatric clearance for suitability are eligible for SCS trials at our center. Pre- and post-flexion radiographs taken immediately after implantation and on postoperative day 1 or 2 were examined to assess the distance of lead migration. Clinically significant lead migration was pre-defined as ≥ 10 mm. Results: The mean (SD) distances of epidural lead migration on postoperative day 1 or 2 were 18.2 (12.9) mm and 19.1 (13.3) mm for the cephalic and caudal leads, respectively. All migrations were caudad except for one trial. Clinically significant lead migration occurred in 20/27 (74 %) patients. Conclusion: Clinically significant epidural lead migration occurs in the early SCS trial period.
