研究目的: |
本研究旨在采用目标试验模拟框架,利用真实世界电子病历数据模拟一项理想化的RCT,以评估AP起病早期(腹痛症状出现48小时内)直肠给予吲哚美辛栓剂相较于不使用该药,在预防7天内新发器官功能衰竭中的因果效应,为吲哚美辛治疗AP提供高质量的循证医学证据。 |

|
Objectives of Study: |
This study aims to evaluate the causal effect of early rectal administration of indomethacin suppositories (within 48 hours of abdominal pain onset) versus no indomethacin on preventing new-onset organ failure within 7 days in patients with acute pancreatitis (AP). To achieve this, we will employ a target trial emulation framework to simulate a hypothetical randomized controlled trial using real-world data from electronic health records. The objective is to provide high-quality, evidence-based medicine to support the therapeutic use of indomethacin for AP. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究为一项基于真实世界数据的目标试验模拟研究,不涉及传统意义上的前瞻性随机分配。患者的分组是根据其在研究时间窗内(零时刻后的12小时宽限期)实际接受的临床治疗而确定的,并非由研究者通过生成随机序列进行分配。 为了在统计分析中模拟随机化的效果,以控制选择偏倚和基线混杂因素,我们将主要采用基于倾向性评分的逆概率治疗加权方法。通过此方法,我们将为每位患者计算一个权重,使得加权后的两组在所有已知的基线混杂因素上达到平衡,从而模拟一个理想化的随机对照试验。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study is a Target Trial Emulation based on real-world data and does not involve prospective randomization in the conventional sense. Patient assignment to a group is determined by the actual clinical treatment they received within the study's time window (a 12-hour grace period after time zero), rather than being allocated by investigators via a random sequence. To emulate the effect of randomization in the statistical analysis and to control for selection bias and baseline confounders, we will primarily employ the propensity score-based inverse probability of treatment weighting method. Through this method, we will calculate a weight for each patient, such that the weighted groups achieve balance on all measured baseline confounders, thereby emulating a hypothetical randomized controlled trial. |
