The evolution of song repertoires and immune defence in birds.
Article in Proceedings. Biological sciences, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Song repertoires (the number of different song types sung by a male) in birds provide males with an advantage in sexual selection because females prefer males with large repertoires, and females may benefit because offspring sired by preferred males have high viability. Furthermore, males with large repertoires suffer less from malarial parasites, indicating that a large repertoire may reflect health status. We hypothesize that sexual selection may cause a coevolutionary increase in parasite virulence and host immune defence because sexual selection increases the risk of multiple infections that select for high virulence. Alternatively, a female mate preference for healthy males will affect the coevolutionary dynamics of host-parasite interactions by selecting for increased virulence and hence high investment by hosts in immune function. In a comparative study of birds, repertoire size and relative size of the spleen, which is an important immune defence organ, were strongly, positively correlated accounting for almost half of the variance. This finding suggests that host-parasite interactions have played an important role in the evolution of song repertoires in birds.
