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
ROSINA (RSI) was isolated as a DNA binding factor able to bind to the CArG-box present in the promoter of the MADS-box gene DEFICIENS of Antirrhinum majus. The mosaic nature of RSI and its multi-copy presence in the A. majus genome indicated that RSI could be a part of a mobile genetic element. Here we show that RSI is a part of a CACTA transposable element system of A. majus, named TamRSI, which has evolved and is still evolving within the terminal inverted repeats (TIRs) of this CACTA transposon. Interestingly, RSI is always found in opposite orientation with respect to the transcription of a second gene present within the CACTA transposon, which encodes a putative TRANSPOSASE (TNP). This structural configuration has not yet been described for any member of the CACTA transposons superfamily. Internal deletion derivatives of the TamRSI produce aberrant RSI transcripts (RSI-ATs) that carry parts of the RSI RNA fused to parts of the TNP RNA. In addition, an intriguing seed phenotype shown by RNAi transgenic lines generated to silence RSI, relate TamRSI to epigenetic mechanisms and associate the control of flower development to transposon activity.
