ResFlow
ResFlow is the flagship of Labs — it strings clinical research into one line, from question to publication. It reorganises 28 research tools by research pipeline and by study type, telling you which tool to use at each step; the core Project workbench lets one dataset flow from modelling to manuscript material. All computation is local — nothing is uploaded.

🧪
I have data — start now
Open the project workbench: paste data once → Table 1 → fit a model → predicted probabilities flow into ROC/calibration/DCA → manuscript material.
🧭
I'm not sure which method
Answer a few questions (comparing what? how many groups? what kind of outcome?) and the advisor names the method and links straight to the tool.

About ResFlow
ResFlow is the flagship of Labs — it strings scattered statistical tools into a complete clinical-research pipeline, so you can see what to do at each step and which tool to use. To grab a single calculator directly, head to the Research tools on the Labs home.
