I am working with a database and want to create a flow chart which shows how many cases are lost as I apply each filtering criteria. In short I want to generate an 'old school' flow chart as appears below. This link shows how to create colour pictures using \usepackage{smartdiagram}, however I want to create a very simple, straight-to-the-point chart. Are there premade packages for this, or must it be built using \usepackage{tikz}?

I suggest to use tikzenter image description here.

    {draw,minimum height=0.7cm,minimum width=2cm,align=center},
    {draw,minimum height=1.3cm,minimum width=3cm,align=center},
    {draw,minimum height=1.5cm,minimum width=3cm,align=center},
  \node[database] (db) {Database\\1995--2015};
  \node[data,below=of db] (d1) {$N=4\,199$};
  \node[data,below=of d1] (d2) {$N=2\,848$};
  \node[data,below=of d2] (d3) {$N=2\,561$};
  \draw[flow] (db) -- (d1);
  \draw[flow] (d1) -- coordinate(d1d2) (d2);
  \draw[flow] (d2) -- coordinate(d2d3) (d3);
  \node[filter,right=of db] (excl) {Exclusions};
  \node[filter] (f1) at (d1d2-|excl) {Males\\($N=250$)};
  \draw[apply] (d1d2) -- (f1);
  \node[filter] (f2) at (d2d3-|excl) {Not Obese\\($N=250$)};
  \draw[apply] (d2d3) -- (f2);

  • Yes, I've done a few fairly simple flowcharts and just used TikZ. In fact they were my first TikZ figures -- it's a good place to learn the basics.
