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

MAIN

conclusionGenetic engineering of Arabidopsis thaliana reveals that mitochondrial serine hydroxymethyltransferase 1 (SHMT1) protein abundance does not limit the capacity of photorespiration, photosynthesis, or stomatal conductance. Photorespiration safeguards photosynthesis from negative metabolic feedback inhibition caused by Rubisco's major oxygenation byproduct, 2-phosphoglycolate, and its downstream metabolites. Previous studies have shown that photosynthetic limitations can be alleviated by enhancing endogenous photorespiratory flux through position-specific enzyme overexpression. Here, we investigated whether overexpression of mitochondrial serine hydroxymethyltransferase 1 (SHMT1) influences this regulatory circuit. However, the 1.3-threefold increase in SHMT1 protein abundance did not affect the visual phenotype, growth, or photosynthetic gas-exchange parameters, including CO
