The CNTR apparatus (also known as the Universal Apparatus) displays all variant readings followed by the witnesses that support them. The CNTR apparatus provides several improvements not normally found in other apparatuses:

• First complete apparatus to show all variants for all early witnesses (most only show about 10% of them).
• Uses a simplified set of symbols that are easier to understand, displayed with user selected base text.
• Displays phonetical word variants by their cononical spellings, ignoring other orthographic differences.
• Displays support from other major critical texts (which can be filtered out if not desired).
• Displays partial matches for readings affected by lacuna.
• Includes English interlinear information (by hovering) so that the average user can get an idea of what they mean.
• Uses algorithmic determined variant unit boundaries.
• Generated directly from the raw manuscript data to help eliminate errors.

The Universal Apparatus currently only contains extant manuscript data from up to 400AD along with some modern critical texts. The probability percentage represents an experimental algorithmic score that is subject to change with advances in data and technology. The “/” before a number indicates its orthographical probability. The percentage is not necessarily intuitive and is not based at all on the unsound concept that the majority rules.
