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
objectiveLumboperitoneal shunt (LPS) surgery is a widely used treatment for normal pressure hydrocephalus (NPH), especially in East Asia. Although LPS surgery has been widely studied internationally, large-scale data from the Republic of Korea are limited. This study aimed to evaluate clinical outcomes and complications of LPS surgery in NPH patients, with particular focus on anesthesia type and valve pressure management strategies.
methodsA retrospective review was conducted of 244 patients with NPH who underwent LPS surgery between February 2020 and February 2025. Valve pressures were initially set at the highest level and gradually adjusted downward based on clinical response. Functional outcomes-including the modified Rankin scale (mRS), timed up and go (TUG), 10-m gait test, and Mini-Mental State Examination (MMSE)-were assessed at 1 year and followed for up to 4 years. Complications were categorized by type and whether surgical intervention was required.
resultsAmong 244 patients, 119 completed at least 1 year of follow-up. At 1 year, 53.8% of patients showed mRS improvement, and 66.4% demonstrated gait improvements (TUG and 10-m walk). Stable or improved function was observed in 93.3% of patients. MMSE scores did not show significant change. The overall complication rate was 16.8%, with 11.1% requiring surgical revision, primarily for chronic subdural hematoma and catheter-related issues. No surgery-related mortality occurred, but three patients (1.2%) died from falls despite improved gait, underscoring the need for fall prevention. The adoption of an initial high-pressure setting reduced overdrainage-related complications, contributing to a decreased annual revision rate of 5.6%.
conclusionA retrospective study showed that LPS surgery with local anesthesia is effective for NPH patients, demonstrating favorable functional outcomes and acceptable complications. Using higher initial valve pressures significantly decreased the need for revision surgeries and complications related to overdrainage.
