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
BACKGROUND AND
aimsINDETERMINATE DOMAIN 10 (IDD10) is a key transcription factor gene that activates the expression of a large number of NH4+-responsive genes including AMMONIUM TRANSPORTER 1;2 (AMT1;2). Primary root growth of rice (Oryza sativa) idd10 mutants is hypersensitive to NH4+. The involvement of CALCINEURIN B-LIKE INTERACTING PROTEIN KINASE (CIPK) genes in the action of IDD10 on NH4+-mediated root growth was investigated.
methodsQuantitative reverse transcription-PCR was used to analyse NH4+- and IDD10-dependent expression of CIPK genes. IDD10-regulated CIPK target genes were identified using electrophoretic mobility shift assays, chromatin immunoprecipitation and transient transcription assays. Root growth rate, ammonium content and 15N uptake of cipk mutants were measured to determine their sensitivity to NH4+ and to compare these phenotypes with those of idd10. The genetic relationship between CIPK9 OX and idd10 was investigated by crosses between the CIPK9 and IDD10 lines. KEY
resultsAMT1;2 was overexpressed in idd10 to determine whether NH4+-hypersensitive root growth of idd10 resulted from limitations in NH4+ uptake or from low cellular levels of NH4+. High NH4+ levels in idd10/AMT1;2 OX did not rescue the root growth defect. Next, the involvement of CIPK genes in NH4+-dependent root growth and interactions between IDD10 and CIPK genes was investigated. Molecular analysis revealed that IDD10 directly activated transcription of CIPK9 and CIPK14. Expression of CIPK8, 9, 14/15 and 23 was sensitive to exogenous NH4+. Further studies revealed that cipk9 and idd10 had almost identical NH4+-sensitive root phenotypes, including low efficiency of 15NH4+ uptake. Analysis of plants containing both idd10 and CIPK9 OX showed that CIPK9 OX could rescue the NH4+-dependent root growth defects of idd10.
conclusionsCIPK9 was involved in NH4+-dependent root growth and appeared to act downstream of IDD10. This information will be useful in future explorations of NH4+ signalling in plants.
