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

CYCS encodes somatic cytochrome c, which plays a central role in the electron transport chain and oxidative phosphorylation. We report nine cases of autosomal dominant, non-syndromic CYCS-related thrombocytopenia in three Japanese families. Patients showed no or mild bleeding tendency, with preserved platelet size and morphology, and without other abnormalities in blood cell lineages. Using targeted gene sequencing for congenital thrombocytopenia, we identified pathogenic missense variants in CYCS, shared by all affected individuals in each family. Two were previously reported: c.274A > G,p.(Arg92Gly) and c.309C > T,p.(Thr103Ile); one was novel: c.212A > C,p.(Asn71Thr). Genetic testing should be considered in unexplained familial thrombocytopenia.
