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
The plant hormone auxin modulates cell proliferation and cell expansion in part by changing gene expression. Among the three primary auxin response gene families, Aux/IAA, GH3 and SAUR, the function of SAUR genes remains unclear. SAUR transcripts were initially identified in epidermal and cortical cells of elongating tissues and thus were supposed to regulate cell expansion downstream of auxin transport and auxin signaling. Recent studies have proposed that SAUR proteins are able to modulate auxin transport and cell expansion by an unknown mechanism. We present our work on the SAUR41 subfamily genes of Arabidopsis (SAUR41, SAUR40, SAUR71 and SAUR72). Similar to the fusion protein between SAUR41 and EGFP, both SAUR40-EGFP and SAUR71-EGFP were identified in the cytoplasm of all types of root tip cells. This result indicated that the subcellular location pattern of SAUR proteins among the members of the same subfamily could be similar to each other, although the overall location pattern of SAUR proteins appeared to be highly diverse. SAUR41 was distinctively expressed in the quiescent center and cortex/endodermis initials of root stem cell niches and in the endodermis of hypocotyls, whereas SAUR71 and SAUR72 were expressed in the steles of young roots and hypocotyls. In addition, SAUR71 was differentially expressed during stomatal formation. The tissue-specific and developmentally regulated expression patterns of the SAUR41 subfamily genes imply that SAUR transcripts or SAUR proteins might serve as signal molecules to ensure the coordination of cell proliferation and cell expansion. Finally, Arabidopsis seedlings expressing TAP (tandem affinity peptide) tagged SAUR41 displayed phenotypes, indicating that it was rational to use the TAP approach for identification of potential binding partners of SAUR41 proteins.
