Bulk Centile Calculator
The bulk centile calculator (BCC) allows the
calculation of customised centiles for
birthweight and ultrasound-derived estimated
fetal weights. It includes 120 coefficient
sets representing ethnic groups / countries
of origin and geographic regions, developed
using anonymised data from more than four
million pregnancies across 33 countries.
The calculator is intended for use by
clinicians, researchers and data analysts
and is provided in two formats depending
on purpose and familiarity with
statistical software:
Bulk Centile Calculator in Excel
-
allows calculation of up to
50,000 rows at a time using
macros within Excel;
-
may require initial set-up
to bypass firewalls due
to macros in application;
-
some users may struggle
with regional or language
related issues in Excel;
-
suitable for audits or analyses
of small to medium size
datasets.
Bulk Centile Calculator in 'R'
-
no fixed limit of number of
births calculated at any time;
-
functions faster than
Excel version;
-
requires some familiarity
with statistical software
'R' and less user-friendly
than the Excel version;
-
intended to be used by
data analysts or researchers
with large datasets.
