A blobbogram is designed to show whether further research is needed. Studies crossing the vertical line are inconclusive. Here the summary (bottom diamond) shows that the treatment prevented babies from dying. Further studies like these are not needed.

The phrases "further research is needed" (FRIN), "more research is needed" and other variants are commonly used in research papers. The cliché is so common that it has attracted research, regulation and cultural commentary.
