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

The antibodies of known three-dimensional structure exhibit a definite number of conformations (canonical structures) for five of six hypervariable loops. In the present study it was found that approximately 85% of the immunoglobulin sequences analyzed fall into a small number of canonical structure combinations, representing only 3% of the total possible. These structures were classified into six distinct groups, depending on the type of antigen with which they interact. Within each loop, the positions responsible for maintaining these canonical structures show a use frequency of amino acids that fits an inverse power law, whereas the use frequency of the amino acids responsible for the detailed antigenic specificity follows an exponential distribution. We propose an evolutionary interpretation that connects these data, using the fact that the inverse power law is generated by statistical processes of the type that yield a wealth curve and the fact that exponential distribution is generated by processes that are not biased by past history.
