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 immutans (im) variegation mutant of Arabidopsis thaliana is caused by an absence of PTOX, a plastid terminal oxidase bearing similarity to mitochondrial alternative oxidase (AOX). In an activation tagging screen for suppressors of im, we identified one suppression line caused by overexpression of AOX2. AOX2 rescued the im defect by replacing the activity of PTOX in the desaturation steps of carotenogenesis. Similar results were obtained when AOX1a was reengineered to target the plastid. Chloroplast-localized AOX2 formed monomers and dimers, reminiscent of AOX regulation in mitochondria. Both AOX2 and AOX1a were present in higher molecular weight complexes in plastid membranes. The presence of these proteins did not generally affect steady state photosynthesis, aside from causing enhanced nonphotochemical quenching in both lines. Because AOX2 was imported into chloroplasts using its own transpeptide, we propose that AOX2 is able to function in chloroplasts to supplement PTOX activity during early events in chloroplast biogenesis. We conclude that the ability of AOX1a and AOX2 to substitute for PTOX in the correct physiological and developmental contexts is a striking example of the capacity of a mitochondrial protein to replace the function of a chloroplast protein and illustrates the plasticity of the photosynthetic apparatus.
