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
backgroundPaddle electrode stimulation of the trigeminal nucleus caudalis (TNC) for refractory craniofacial pain syndromes provides improved coverage and has lower migration rates than cylindrical leads; however, paddle implantation requires open surgery, which can cause significant pain and limit use in high-risk patients. Herein, the authors present a minimally invasive (MIS) approach, adapting the use of tubular retractors for MIS spine surgery and therefore minimizing the surgical morbidity of paddle electrode implantation at the craniocervical junction. OBSERVATIONS: An 81-year-old man with postherpetic trigeminal neuropathy in the left V1 and V2 distribution underwent paddle lead implantation via a 2.5-cm occipitocervical incision and a tubular retractor system. The patient experienced a reduction in pain (from a visual analog scale score of 9/10 to 2/10), without any postoperative complications. LESSONS: This technical report demonstrates the feasibility of implanting paddle electrodes via an MIS tubular retractor system for stimulating the TNC. The approach minimizes soft tissue disruption, reduces postoperative pain, and offers a viable alternative to open surgery, which is especially useful for medically complex patients requiring neuromodulation for craniofacial pain. https://thejns.org/doi/10.3171/CASE25721.
