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
Morphological novelties arise through changes in development, but the underlying causes of such changes are largely unknown. In the genus Physalis, sepals resume growth after pollination to encapsulate the mature fruit, forming the "Chinese lantern," a trait also termed inflated-calyx syndrome (ICS). STMADS16, which encodes a MADS-box transcription factor, is expressed only in vegetative tissues in Solanum tuberosum. Its ortholog in Physalis pubescens, MPF2, is expressed in floral tissues. Knockdown of MPF2 function in Physalis by RNA interference (RNAi) reveals that MPF2 function is essential for the development of the ICS. The phenotypes of transgenic S. tuberosum plants that overexpress MPF2 or STMADS16 corroborate these findings: these plants display enlarged sepals. Although heterotopic expression of MPF2 is crucial for ICS, remarkably, fertilization is also required. Although the ICS is less prominent or absent in the knockdown transgenic plants, epidermal cells are larger, suggesting that MPF2 exerts its function by inhibiting cell elongation and promoting cell division. In addition, severely affected Physalis knockdown lines are male sterile. Thus, heterotopic expression of MPF2 in floral tissues is involved in two novel traits: expression of the ICS and control of male fertility. Sequence differences between the promoter regions of the MPF2 and STMADS16 genes perhaps reflect exposure to different selection pressures during evolution, and correlate with the observed differences in their expression patterns. In any case, the effects of heterotopic expression of MPF2 underline the importance of recruitment of preexisting transcription factors in the evolution of novel floral traits.
