1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

contextSemiempirical computational methods based on the MNDO approximation have a long history. Since its release in 1977, the original MNDO method has evolved steadily, passing through several forms (AM1, PM3, etc.) up to the present. Each new form represented an improvement, and it is anticipated that the evolution will continue for many more years.

methodsA summary of the history of MNDO-based methods will be given, followed by a description of the mechanisms involved in developing some of the current methods. To assist in this, a set of files illustrating the steps and procedures involved is provided in Supporting Material; hopefully these will be useful in facilitating the development of future methods.
