Activation of Rubisco controls CO(2) assimilation in light: a perspective on its discovery.
Article in Photosynthesis research, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
CO(2) fixation during photosynthesis is regulated by the activity of ribulose bisphosphate carboxylase (Rubisco). This conclusion became more apparent to me after CO(2)-fixation experiments using isolated spinach chloroplasts and protoplasts, purified Rubisco enzyme, and intact leaves. Ribulose bisphosphate (RuBP) pools and activation of Rubisco were measured and compared to (14)CO(2) fixation in light. The rates of (14)CO (2) assimilation best followed the changes in Rubisco activation under moderate to high light intensities. RuBP pool sizes regulated (14) (2) assimilation only in very high CO(2) levels, low light and in darkness. Activation of Rubisco involves two separate processes: carbamylation of the protein and removal of inhibitors blocking carbamylation or blocking RuBP binding to carbamylated sites before reaction with CO(2) or O(2).
