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

Chlorophycean algae of the genera Chlamydomonas and Polytomella share a common photosynthetic ancestor. However, members of the Polytomella lineage have adopted a heterotrophic lifestyle, having lost the photosynthetic apparatus and relying instead on acetate or ethanol as carbon sources, with energy production centered on oxidative phosphorylation (OXPHOS). In this study, we investigated the composition of the mitochondrial supercomplexes of the colorless alga Polytomella parva. Mitochondrial membranes were solubilized using mild detergents such as glycol-diosgenin and digitonin, followed by separation of OXPHOS complexes supramolecular assemblies via Blue Native electrophoresis and Fast Protein Liquid Chromatography (FPLC). Additionally, complexome profiling of solubilized algal mitochondria resolved by Blue Native Gel Electrophoresis was carried out (data are available via ProteomeXchange with identifier PXD075371). The resulting data indicate that the OXPHOS supercomplexes of Polytomella closely resemble those observed in situ in the mitochondria of its green relative Chlamydomonas reinhardtii, as revealed by electron cryo-tomography and subtomogram averaging.
