DashKaplanMeier Dash Component Hello community. Here I present a Dash component to render Kaplan–Meier survival curves with enhanced interactivity and styling options. DashKaplanMeier component plots multiple Kaplan-Meier curves with confident intervals and computes its statistics (logrank p-value,…

very cool, @Xavi.LL . What are Kaplan–Meier survival curves used for? Did you do this as part of your work or part of a hobby?

Hi @adamschroeder , i’m working in cancer research, where the Kaplan-Meier survival curves are widely used by bioinformaticians or clinicians to compare groups of patients, samples, treatments and more. Since some years I’m using plotly and dash for interactive visualizations, but I din’t see a Kapl…

very interesting, and sounds quite useful to people in the field. Thank you for creating this component, @Xavi.LL :folded_hands:

Very interesting. Scikit-learn library has also a type of kaplan-meier estimator. Scikit-survival. Well Is not part of the core, Is built on top of scikit specifically for survival analysis

Hi @Avacsiglo21 , you’re absolutely right. The DashKaplanMeier component I have created use the Python library called lifelines to compute the survival curves, so the good things are, that you don’t need to use this analysis libraries because the DashKaplanMeier compute the survival curves for you…

Hi @YaKuzuri , thanks for your comment. I’m very happy that this component can simplify your analysis. I’ll have a look at the showStatistics, where is the mistake. I imagine you compute the statistics (stats = compute_survival_stats(time ,event, group) before the Dash app declaration right? Could …

app = Dash() app.layout = [ html.H1(children='Title of Dash App', style={'textAlign':'center'}), html.A(href='http://127.0.0.1:8000', children='На главную страницу', style={'textAlign':'center'}), html.Button('Обновить базу', id='reload_btn', n_clicks=0), html.Div(id='reload_div') ]…

Thanks @YaKuzuri for the example. To me it worked. I’m using: dash==3.0.4 pandas==2.3.0 lifelines==0.30.0 numpy==2.2.6 Also check that: Time values are float type. Event values are int type (0 or 1). Group values are str. Ensure that all required props are passed and have correct numeric val…

You’re welcome @adamschroeder . When I started using Plotly and Dash, I was a bit surprised that a Kaplan-Meier component was not included in the Dash Bio components. In my field, Kapla-Meier plots are more used than some plots in Dash Bio, which are also useful an super interesting. Maybe you can i…

Hi @Xavi.LL , thank you for this component! I’m oncologist from N. N. Alexandrov National Cancer Centre of Belarus and I’ve looked for something like this. But showStatistics=True does not work. I’m using Dash 3.0.4
