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
Zea nicaraguensis is a wild relative of Zea mays subsp. mays (maize) that has high waterlogging tolerance. One of its traits is constitutive aerenchyma formation (CAF) in roots and this may be one of the reasons for the tolerance, but it has not yet been proven by comparing plants that differ only in CAF in the same genetic background. We therefore produced an introgression line AE24-50-44-91 (IL-AE91) possessing four quantitative trait loci for CAF from Z. nicaraguensis in the background of maize (inbred line Mi29). The degree of root CAF in IL-AE91 was intermediate between that of Mi29 and Z. nicaraguensis. Seedlings of IL-AE91 grown aerobically were more tolerant to transfer to oxygen-deficient conditions than were Mi29 seedlings. On day 2 of oxygen deficiency, the root extension rate and viability of root-tip cells in IL-AE91 were ~2.7 and ~1.3 times greater, respectively, than they were in Mi29. On day 4, the area of aerenchyma at 80 mm from the root tips was ~1.5 times greater in IL-AE91 and radial oxygen loss from the apical parts of roots was ~3.4 times higher than in Mi29. These results demonstrate that CAF reduces the stress from low external oxygen levels caused by soil waterlogging.
