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

In this paper, we investigate a simple protein sequence conservation measure which takes amino acid similarity into account. Instead of grouping 20 amino acids into disjoint sets in previous methods, we consider ten overlapping classes. The method is based on the assumption that a column in a multiple sequence alignment is evolved from an identical column in the evolutionary history. Two ten-dimensional vectors are constructed for each position to denote frequencies of ten classes in a column and the corresponding hypothetical identical column. Then the cosine function of the angle between these two vectors is considered as a measure of divergence of stereochemical properties at this position. This divergence, combining with other conservation scores, is used as conservation measure of the column. Finally, we evaluate our methods by identifying catalytic sites, using rank analysis criterion and receiver operator characteristic analysis criterion.
