<b>Comparative Evaluation of Modified Alvarado Score and Anderson Score for Predicting Acute Appendicitis: An Analytical Cross-Sectional Study</b>

This is data obtained while doing a prospective, analytical, hospital-based cross-sectional study of 71 consecutive patients who presented to the emergency room at Bir Hospital, Nepal with symptoms suggestive of acute appendicitis was carried out. Modified Alvarado score and Anderson score were calculated after taking into account the patient's medical history, clinical examination, and pertinent laboratory investigations. Regarding Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value, and Diagnostic Accuracy to predict acute appendicitis, these scores were compared to the Histopathology report following an appendectomy based on the operating surgeon's decision.From the study of data from 71 patients the mean age of 29.68 ±10.88 years with Male to female ratio of 1.08:1. Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value, and Accuracy for the Modified Alvarado Score and Anderson Score respectively were 77 % vs. 93.4%; 60% vs. 80%; 88.23% vs. 96.6%; 30% vs. 66.6%; and 53% vs.93.4 %. The negative Appendectomy Rate was 14.08%. Thus<b>, </b>Anderson scores have better sensitivity, specificity, Positive predictive value, and accuracy for diagnosis of Acute Appendicitis than the Modified Alvarado Score but have more negative predictive value compared to the Modified Alvarado Score.本研究针对尼泊尔比尔医院急诊室就诊的71例连续出现疑似急性阑尾炎（Acute Appendicitis）症状的患者，开展一项前瞻性、分析性、基于医院的横断面研究，本数据集即来源于该研究的采集数据。研究人员在收集患者病史、临床体格检查及相关实验室检查结果后，计算了改良阿尔瓦拉多评分（Modified Alvarado Score）与安德森评分（Anderson Score）。以手术医师依据临床决策实施阑尾切除术（Appendectomy）后获取的组织病理学（Histopathology）报告为金标准，对比两种评分系统在预测急性阑尾炎时的灵敏度（Sensitivity）、特异度（Specificity）、阳性预测值（Positive Predictive Value）、阴性预测值（Negative Predictive Value）及诊断准确度（Diagnostic Accuracy）。 本研究纳入的71例患者平均年龄为29.68±10.88岁，男女比例为1.08:1。改良阿尔瓦拉多评分与安德森评分对应的灵敏度、特异度、阳性预测值、阴性预测值及诊断准确度分别为：77%与93.4%；60%与80%；88.23%与96.6%；30%与66.6%；53%与93.4%。阴性阑尾切除率为14.08%。 综上，相较于改良阿尔瓦拉多评分，安德森评分在急性阑尾炎诊断中具有更优的灵敏度、特异度、阳性预测值及诊断准确度，但其阴性预测值更高。

背景概述

该数据集基于一项针对71名急性阑尾炎疑似患者的医院横断面研究，比较了改良Alvarado评分和Anderson评分在预测急性阑尾炎中的诊断性能。结果显示Anderson评分在敏感性、特异性、阳性预测值和准确性方面更优，但阴性预测值较低，数据集包含患者临床数据和评分结果，适用于外科和急诊医学研究。
