Internal architecture of mitochondrial complex I from Arabidopsis thaliana.
Article in The Plant cell, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 78 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
The NADH dehydrogenase complex (complex I) of the respiratory chain has unique features in plants. It is the main entrance site for electrons into the respiratory electron transfer chain, has a role in maintaining the redox balance of the entire plant cell and additionally comprises enzymatic side activities essential for other metabolic pathways. Here, we present a proteomic investigation to elucidate its internal structure. Arabidopsis thaliana complex I was purified by a gentle biochemical procedure that includes a cytochrome c-mediated depletion of other respiratory protein complexes. To examine its internal subunit arrangement, isolated complex I was dissected into subcomplexes. Controlled disassembly of the holo complex (1000 kD) by low-concentration SDS treatment produced 10 subcomplexes of 550, 450, 370, 270, 240, 210, 160, 140, 140, and 85 kD. Systematic analyses of subunit composition by mass spectrometry gave insights into subunit arrangement within complex I. Overall, Arabidopsis complex I includes at least 49 subunits, 17 of which are unique to plants. Subunits form subcomplexes analogous to the known functional modules of complex I from heterotrophic eukaryotes (the so-called N-, Q-, and P-modules), but also additional modules, most notably an 85-kD domain including gamma-type carbonic anhydrases. Based on topological information for many of its subunits, we present a model of the internal architecture of plant complex I.
