研究目的: |
探讨乳酸脱氢酶/白蛋白比值(LDH/白蛋白)与 IgA 肾病(IgAN)患者中重度肾小管间质纤维化(牛津分型 T1+T2)的独立相关性,评估该比值作为无创生物标志物识别中重度纤维化的临床价值。 |

|
Objectives of Study: |
To investigate the independent association between lactate dehydrogenase‑to‑albumin ratio (LDH/albumin ratio) and moderate‑to‑severe tubulointerstitial fibrosis (Oxford T1+T2) in patients with IgA nephropathy (IgAN), and to evaluate its discriminative ability as a non‑invasive biomarker for identifying moderate‑to‑severe fibrosis. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究采用病例报告表(CRF)收集患者临床、实验室及病理数据,包括人口学信息、既往病史、肾活检时血液生化指标、牛津分型MEST-C评分等。所有数据由两名研究人员独立核对,缺失数据通过查阅原始病历补充。数据录入使用Microsoft Excel软件,最终数据集以CSV格式存储并采用R软件进行数据清洗与统计分析。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
A standardized case report form (CRF) was used to collect clinical, laboratory and pathological data, including demographics, medical history, blood biochemical parameters at the time of renal biopsy, and Oxford MEST-C scores. All data were independently verified by two researchers; missing data were retrieved from original medical records when possible. Data entry was performed using Microsoft Excel, and the final dataset was stored in CSV format. Data cleaning and statistical analyses were conducted using R software. |
