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
backgroundSpinal Cord Stimulation (SCS) is an established therapy for chronic pain, employing screening trials to identify suitable candidates before implantation. However, complications arising from both technique and medical factors present challenges to this practice. This study introduces the Dural Substitute Confetti technique, which addresses technique-related complications during SCS implantation by preventing scar-induced lead migration or breakage and reducing operating times.
methodsWe conducted a retrospective analysis on 174 patients treated with SCS trials from 2017 to 2022 at our institution. Of these, 85.1% proceeded to permanent implantation. During trial surgery, synthetic dural substitutes (DS) were used to protect leads, which remained connected to an external pulse generator (EPG) for 20-28 days (mean 21.4 days). Utilizing the DS Confetti technique, leads were easily dissected from the DS during the second surgery and connected to an internal pulse generator (IPG). We compared complications and surgical times before and after the introduction of this technique in 2017.
resultsFollowing the complete SCS trial, patients experienced over 50% pain relief, with an implant-to-trial ratio of 85.1% and a mean follow-up of 52 months. No technique-related complications occurred during the trial period post-2017, while the pre-2017 group had a 3.9% lead migration rate due to scarring, necessitating re-implantation. The average surgery duration decreased from 54 min pre-2017 to 32 min post-2017. Medical-related complications included infections (2.1%) and wound dehiscence (1.3%).
conclusionsThe DS Confetti technique prevents scar adhesion formation during screening trials, thereby facilitating and expediting the definitive SCS implantation. Additionally, it may also reduce the risk of lead migration and iatrogenic damage, potentially lowering technique-related complications.
