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 heterocystous nitrogen-fixing cyanobacterium, Anabaena sp. strain PCC7120 displayed two superoxide dismutase (SOD) activities, namely FeSOD and MnSOD. Prolonged exposure of Anabaena PCC7120 cells to methyl viologen mediated oxidative stress resulted in loss of both SOD activities and induced cell lysis. The two SOD proteins were individually overexpressed constitutively in Anabaena PCC7120, by genetic manipulation. Under nitrogen-fixing conditions, overexpression of MnSOD (sodA) enhanced oxidative stress tolerance, while FeSOD (sodB) overexpression was detrimental. Under nitrogen supplemented conditions, overexpression of either SOD protein, especially FeSOD, conferred significant tolerance against oxidative stress. The results demonstrate a nitrogen status-dependent protective role of individual superoxide dismutases in Anabaena PCC7120 during oxidative stress.
