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

Paternal epigenetic inheritance remains mechanistically unresolved. Recent studies propose that environmental exposures induce mitochondrial DNA (mtDNA)-dependent transcription in sperm during epididymal transit, altering small RNA content and offspring phenotypes. Here, we show that mature murine sperm are effectively devoid of mtDNA, precluding mtDNA-dependent transcription, and that sperm-borne mitochondrial RNAs originate during spermatogenesis. Testicular sperm transmitted diet-induced metabolic traits as efficiently as, and in most cohorts more efficiently than, epididymal sperm. These findings establish testicular inheritance independent of sperm mtDNA transcription and epididymal exposure.
