edc-analytics 1.0.2

Overview

Read your data into a dataframe, for example an EDC screening table:

import pandas as pd
from django_pandas.io import read_frame
from meta_screening.models import SubjectScreening
from edc_analytics.custom_tables import AgeTable, GenderTable

qs_screening = SubjectScreening.objects.all()
df = read_frame(qs_screening)

Convert all numerics to pandas numerics:

cols = [
    "age_in_years",
    "dia_blood_pressure_avg",
    "fbg_value",
    "hba1c_value",
    "ogtt_value",
    "sys_blood_pressure_avg",
]
df[cols] = df[cols].apply(pd.to_numeric)

Pass the dataframe to each Table class

gender_tbl = GenderTable(main_df=df)
age_tbl = AgeTable(main_df=df)
bp_table = BpTable(main_df=df)

In the Table instance,

• data_df is the supporting dataframe

• table_df is the dataframe to display. The table_df displays formatted data in the first 5 columns (“Characteristic”, “Statistic”, “F”, “M”, “All”). The table_df has additional columns that contain the statistics used for the statistics displayed in columns [“F”, “M”, “All”].

From above, gender_tbl.table_df is just a dataframe and can be combined with other table_df dataframes using pd.concat() to make a single table_df.

table_df = pd.concat(
    [gender_tbl.table_df, age_tbl.table_df, bp_table.table_df]
 )

Show just the first 5 columns:

table_df.iloc[:, :5]

Like any dataframe, you can export to csv:

path = "my/path/to/csv/folder/table_df.csv"
table_df.to_csv(path_or_buf=path, encoding="utf-8", index=0, sep="|")

| Characteristic | Statistic | F      | M     | All  |
======================================================
| Age (years)    | n         |  1175  | 1000  | 2175 |
|                | 18-34     |    70  |   64  |  134 |
|                | ...etc    |        |       |      |

Putting together a table

RowDefinitions

RowDefinitions are a collection of RowDefinition.

To build a table use the Table class and override the build_defs method. For example:
