Multicenter normative data for mesopic microperimetry

This record contains the analysis and underyling data presented in the manuscript Pfau et al. 'Multicenter normative data for mesopic microperimetry'. Contents: 2024-08-30_Multicenter-Normal-Data.csv: Newly published normal data for mesopic microperimetry 2024-08-30_Analysis.R: Analysis script 2024-08-30_Vignette-to-create-normal-data.R: Software example to create normative maps The subfolders Figures and Tables show the analysis results. The folder Intermediary_Results contains the results of the cross-validation folds to assess model perfromance. To run the analysis code in 2024-08-30_Analysis.R, the following data is needed in addition: Astle et al. Data Brief. 2016 Aug 4;9:673-675. doi: 10.1016/j.dib.2016.07.061 The 2024-08-30_Multicenter-Normal-Data.csv file with the data contains the following columns: source: Describes the clinical site MachineID: ID of the MAIA device used for data collection ParticipantID: ID of the participant EID: ID of the eye eye: Laterality (either Right or Left) sex: Sex (f for female, m for male) age: Age in years ExamID: ID of the exam ExamBaselineID: ID of the corresponding baseline exam (-1 indicates that the exam itself is the baseline exam) GridUsed: Name of the grid falsepos: Rate of false positive responses to Heijl-Krakau stimulus presentations to the optic nerve head (blind spot) bcea63_area_deg2: Fixation stability in terms of the bivariate contour ellipse area covering 63% of the fixation points (in square degree) bcea95_area_deg2: Fixation stability in terms of the bivariate contour ellipse area covering 95% of the fixation points (in square degree) pointID: ID of the test point eccentricity: Eccentricity of the test point (in degree) x_coord: X-coordinate of the test point (in degree), negative values are temporal to the fovea and positive values are nasal to the fovea (in retinal space) y_coord: Y-coordinate of the test point (in degree), negative values are inferior to the fovea and positive values are superior to the fovea (in retinal space) sensitivity: Sensitivity at the test point (in dB)本数据集涵盖Pfau等人发表于论文《"Multicenter normative data for mesopic microperimetry"》的分析内容与原始实验数据。 数据集具体内容如下： 1. 2024-08-30_Multicenter-Normal-Data.csv：最新发布的中间视觉微视野检查（mesopic microperimetry）正常数据集 2. 2024-08-30_Analysis.R：数据分析脚本 3. 2024-08-30_Vignette-to-create-normal-data.R：用于生成正常参考图的软件示例脚本 子文件夹说明： - 文件夹Figures与Tables存放本次分析的结果图表与表格 - 文件夹Intermediary_Results存放用于评估模型性能的交叉验证折次结果 运行2024-08-30_Analysis.R所需的额外补充数据来自：Astle et al.
