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
Background: The application of percutaneous endoscopic lumbar surgery under local anesthesia is becoming increasingly widespread; however, the impact of preoperative psychological status on surgical outcomes remains unclear. This study utilized propensity score matching to evaluate the effects of psychological distress and pain catastrophizing on clinical outcomes. Methods: A retrospective cohort of 148 propensity-score-matched patients (74 per group) undergoing percutaneous endoscopic lumbar discectomy under local anesthesia was analyzed. Preoperative psychological status was assessed using the Hospital Anxiety and Depression Scale (HADS) and the Pain Catastrophizing Scale (PCS). Outcome measures included the Visual Analog Scale (VAS) for leg and back pain, the Oswestry Disability Index (ODI), the Modified MacNab criteria, and the achievement rate of the Minimal Clinically Important Difference (MCID) at 12 months postoperatively. Results: At baseline, no significant differences were observed between the distress and non-distress groups in leg VAS (7.6 ± 2.3 vs. 7.5 ± 2.2, Conclusion: Preoperative psychological distress and pain catastrophizing are independent predictors of inferior clinical outcomes following percutaneous endoscopic lumbar surgery under local anesthesia. Routine preoperative psychological screening and targeted interventions may be beneficial for optimizing surgical outcomes.
