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
backgroundFull endoscopic spine surgery via a transforaminal approach (FESS-TFA) offers a minimally invasive approach for spinal decompression. However, it carries a risk of nerve root irritation or injury. Existing intraoperative neuromonitoring primarily provides retrospective warnings of potential nerve disturbance.
objectiveTo introduce the use of stimulated electromyography neuromonitoring dilators in FESS-TFA for proactive nerve protection, enhanced localization, and potential reduction in radiation exposure.
methodsThis technical note describes the first use of neuromonitoring dilators in FESS-TFA. A 6-mm dilator tipped with a stimulation electrode is introduced to provide real-time directional feedback regarding nerve proximity, allowing the surgeon to actively avoid accidental injury to the exiting nerve root. With the creation of a safe tract, subsequent introduction of working instruments would theoretically reduce the risk of neural injury.
resultsThe technique was successfully applied in a case of T11/T12 severe spinal stenosis, facilitating safe instrument passage and nerve localization. We describe the surgical technique and provide illustrative intraoperative details.
conclusionNeuromonitoring dilators represent a promising innovation in FESS-TFA with the potential to enhance patient safety and possibly streamline the procedure. Larger-scale studies are warranted to quantify the true impact of this technique on complication rates, operative time, and radiation exposure. CLINICAL RELEVANCE: This technique highlights a significant advancement in reducing neural complications during minimally invasive spinal surgeries. By proactively preventing nerve irritation or injury and reducing radiation exposure, it contributes to optimizing surgical workflows and improving patient outcomes. LEVEL OF EVIDENCE: 5:
