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

High levels of MHC diversity are crucial for immunological fitness of populations, with island populations particularly susceptible to loss of genetic diversity. In this study, the level of MHC class II DBB diversity was examined in tammar wallabies (Macropus eugenii) from Kangaroo Island by genotyping class II-linked microsatellite loci and sequencing of DBB genes. Here we show that the tammar wallaby has at least four expressed MHC class II DBB loci and extensive genetic variation in the peptide-binding region of the DBB genes. These results contradict early studies which suggested that wallabies lacked MHC class II diversity and demonstrate that, in spite of the long-term isolation on an offshore island, this population of wallabies has a high level of DBB diversity.
