1 · What the graph read from it

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.

2 · The registry

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

backgroundNeuroinflammation may be involved in the pathogenesis of idiopathic normal pressure hydrocephalus (iNPH). However, the specific changes in the peripheral inflammatory state of patients with iNPH remain unclear.

objectiveTo explore the changes in the peripheral inflammatory state of patients with iNPH and their potential value as biomarkers of clinical diagnosis and disease severity.

methodsIn this cross-sectional study, 119 iNPH patients with AD-negative pathology and 200 healthy controls (HCs) were enrolled. Clinical characteristics, including the Idiopathic Normal Pressure Hydrocephalus Grading Scale (iNPHGS), Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), were collected along with inflammatory parameters in the peripheral blood. Logistic regression was applied to evaluate differences in peripheral inflammatory indicators, adjusting for age, sex, and comorbidities. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance of the inflammatory markers. Correlations between inflammatory parameters and clinical characteristics were assessed.

resultsSignificant differences in inflammatory parameters, such as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and prognostic nutritional index (PNI), were observed between iNPH patients and HCs after adjusting for age, sex and comorbidities. The combination of PNI and platelet-to-high-density lipoprotein ratio (PHR) distinguished iNPH patients from HCs most significantly (area under the curve [AUC] = 0.820). Neutrophil ratio and lymphocyte ratio were associated with clinical severity and cognitive impairment of patients with iNPH.

conclusionsiNPH patients exhibit an elevated peripheral inflammatory state. Peripheral inflammatory parameters, especially neutrophil ratio and lymphocyte ratio, are associated with disease severity and cognitive impairment, suggesting their potential as therapeutic targets and offering new insights into the pathophysiology of iNPH. Additionally, the inflammatory peripheral parameters may serve as valuable and convenient method in assisting clinical diagnosis.
