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
Late embryogenesis abundant (LEA) proteins have been implicated in many stress responses of plants. In this report, a LEA protein gene OsLEA3-1 was identified and over-expressed in rice to test the drought resistance of transgenic lines under the field conditions. OsLEA3-1 is induced by drought, salt and abscisic acid (ABA), but not by cold stress. The promoter of OsLEA3-1 isolated from the upland rice IRAT109 exhibits strong activity under drought- and salt-stress conditions. Three expression constructs consisting of the full-length cDNA driven by the drought-inducible promoter of OsLEA3-1 (OsLEA3-H), the CaMV 35S promoter (OsLEA3-S), and the rice Actin1 promoter (OsLEA3-A) were transformed into the drought-sensitive japonica rice Zhonghua 11. Drought resistance pre-screening of T(1) families at anthesis stage revealed that the over-expressing families with OsLEA3-S and OsLEA3-H constructs had significantly higher relative yield (yield under drought stress treatment/yield under normal growth conditions) than the wild type under drought stress conditions, although a yield penalty existed in T(1) families under normal growth conditions. Nine homozygous families, exhibiting over-expression of a single-copy of the transgene and relatively low yield penalty in the T(1) generation, were tested in the field for drought resistance in the T(2) and T(3) generations and in the PVC pipes for drought tolerance in the T(2) generation. Except for two families (transformed with OsLEA3-A), all the other families (transformed with OsLEA3-S and OsLEA3-H constructs) had higher grain yield than the wild type under drought stress in both the field and the PVC pipes conditions. No significant yield penalty was detected for these T(2 )and T(3) families. These results indicate that transgenic rice with significantly enhanced drought resistance and without yield penalty can be generated by over-expressing OsLEA3-1 gene with appropriate promoters and following a bipartite (stress and non-stress) in-field screening protocol.
