Kaplan-Meier survival curves comparing academic and non-academic facility groups
Kaplan-Meier curves became the clearest visual summary: facility type, survival time, and cohort filtering all converge in one figure.

Evidence Trail

Who entered the study?

PRISMA diagram showing cohort selection
The PRISMA flow is the starting point: it shows exactly how the database population narrowed into the analyzable cohort.

How was disease grouped?

Tumor grade analysis figure
Tumor-grade grouping set the comparison structure, keeping downstream survival and palliative-care analyses clinically grounded.

What changed over time?

Kaplan-Meier survival curve figure
The survival curves turn the cleaned cohort into the main takeaway: outcomes can be compared without rereading the full analysis script.
