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

Chrysophytes are nanoflagellate protists widespread in aquatic ecosystems with diverse trophic roles as primary producers and bacterivores. Molecular evidence suggests that chrysophytes are commonly infected by giant viruses, but isolates of such virus-host systems have not been reported. Here, we describe the first cultivated chrysophyte-infecting virus, Chrysophyceae Clade H virus SA1 (ChrysoHV), isolated along with its phago-mixotrophic host alga from surface waters in the tropical North Pacific Ocean. The ChrysoHV capsid (290 ± 40 nm diameter) is associated with a loose, sac-like membrane that extends its effective diameter (720 ± 120 nm) and presents a long (1,200 ± 240 nm), thin (20 ± 2 nm), flexible tail, a morphology unlike any virion yet described. The assembled genome is 1.19 Mbp. Phylogenetic analysis places ChrysoHV as the third cultivated member of the
