Clinical research is the study of patients with the aim of improving care. Our objectives were to calculate the percentage of presentations at territorial section meetings of the Spanish Academy of Dermatology and Venereology (AEDV) that described clinical research, to assess the level of evidence the research provided, and to analyze change in clinical research volume over time.
We reviewed supplements of the journal Actas Dermo-Sifiliográficas for 2000 through 2015 that contained abstracts of presentations given at the AEDV section meetings in Galicia; the area comprising Asturias, Cantabria, and Castile-Leon (ACCL); and Andalusia. We selected abstracts that met a previously validated definition of clinical research and categorized each according to level of evidence. We also analyzed how the weight of clinical research presentations changed over time.
Of the total of 1,188 presentations, 29.6% met the criteria that defined clinical research. Most provided level-4 evidence (95.2%); 44.2% of those presentations reported cross-sectional studies and 55.8% analyzed case series. Clinical research accounted for 26.6% of the presentations in Galicia (94.7% of them, level 4), 22.7% of those at the ACCL meeting (97.6%, level 4), and 37.2% of those in Andalusia (94.3%, level 4). The proportion of clinical research increased significantly over the years studied.
Clinical research accounted for 29.6% of the communications presented at the meetings we reviewed. Most of these presentations concerned case series or cross-sectional studies. The prevalence of clinical research presentations differed between the 3 territories studied, but the levels of evidence were similar. The proportion of clinical research in the programs of these meetings has increased over time.
临床研究是以改善医疗护理为目的对患者进行的研究。我们的目标是计算在西班牙皮肤病学和性病学学会（AEDV）地区分会会议上描述临床研究的报告所占的百分比，评估研究所提供的证据水平，并分析临床研究数量随时间的变化。
我们查阅了《皮肤病与梅毒学学报》2000年至2015年的增刊，其中包含在加利西亚、阿斯图里亚斯、坎塔布里亚和卡斯蒂利亚-莱昂地区（ACCL）以及安达卢西亚的AEDV分会会议上发表的报告摘要。我们选择了符合先前验证的临床研究定义的摘要，并根据证据水平对每篇摘要进行分类。我们还分析了临床研究报告的比重随时间的变化情况。
在总共1188份报告中，29.6%符合临床研究的定义标准。大多数提供了4级证据（95.2%）；其中44.2%的报告为横断面研究，55.8%分析了病例系列。临床研究在加利西亚的报告中占26.6%（其中94.7%为4级），在ACCL会议的报告中占22.7%（97.6%为4级），在安达卢西亚的报告中占37.2%（94.3%为4级）。在研究的这些年里，临床研究的比例显著增加。
在我们查阅的会议上，临床研究占所发表报告的29.6%。这些报告大多涉及病例系列或横断面研究。在所研究的三个地区，临床研究报告的比例有所不同，但证据水平相似。这些会议议程中临床研究的比例随时间有所增加。
