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
With the changing climate and rainfall abrasions, there is a gradual shift in the system of rice cultivation from traditional transplanted anaerobic to aerobic system. Studies on the root anatomical and morpho-physiological traits provide insights about the adaptation under aerobic conditions. We investigated the root anatomical and morpho-physiological traits in anaerobic (BPT 5204) and aerobic (CR Dhan 202) adapted rice genotypes grown under anaerobic and aerobic conditions. It was observed that the formation of fewer aerenchyma, thickened root and larger xylem area were critical anatomical traits associated with aerobic adaptation as compared to anaerobic conditions. The root length of CR Dhan 202 significantly increased under aerobic condition which may be attributed to its aerobic adaptation in terms of water acquisition. The photosynthetic rate was significantly higher in CR Dhan 202 as compared to that of BPT 5204 under the aerobic condition. The morpho-physiological results showed that the root length, total dry weight and photosynthetic rate are the key parameters for imparting aerobic adaptation. These root anatomical and morpho-physiological traits associated with the adaptation can be used as screening criteria for phenotyping and selection of genotypes suitable for aerobic system of cultivation. Such study is expected to expedite the development of rice aerobic varieties in aerobic breeding programmes.
