The datasets are provided as medians and interquartile ranges. Can we perform a pooled analysis? How do we convert variables to get the events as (N)?
When you have data presented in the median and interquartile range (IQR) and you want to perform a pooled analysis to calculate proportions, you may face a challenge because the median and IQR summarize the central tendency and spread of the data. Still, they do not provide information about individual data points.
Proportions are typically calculated based on the counts of events or observations concerning the total number of events or observations. You need the actual data values rather than summary statistics like median and IQR to calculate proportions.
If your goal is to perform a pooled analysis and calculate proportions, you would ideally need access to the raw data or summary statistics that allow for the computation of proportions. If obtaining the individual data is impossible, you may need to explore alternative statistical methods or approaches that can accommodate summary statistics like medians and IQR.
If the median and IQR are the only summary statistics available, you might consider reaching out to the original data sources or authors of the study to request the raw data or additional information that would allow for more detailed analysis, including the calculation of proportions.
Descriptive statistics we can find out median e.g: scores and interval data we can find out range and ratio data also we can find out range....Interquartile range we want use for descriptive statistics
