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
We have explored a modified cytosolic yeast-two-hybrid Sos-recruitment system (SRS) in order to test for membrane localization of a protein. In this system, membrane localization is assessed by rescue of a yeast strain carrying a temperature-sensitive mutation in the CDC25 gene (cdc25-2) at restrictive temperature. The homologous human Sos (hSos) is capable to replace cdc25-2 provided that it is attached to the membrane because only then hSos is functional. This can be achieved when hSos is artificially fused to a protein containing trans-membrane domains (Tms). GFP/YFP fusion construct analyses of the Arabidopsis thaliana PEPINO/PASTICCINO2 (PEP/PAS2) protein have previously shown disparate cellular localizations although this protein possesses clear Tms. Analysis of N-terminal and C-terminal hSos-PEP/PAS2 fusions respectively suggests, that PEP/PAS2 is an integral membrane protein with cytosolic N- and C-termini. This implies that the protein has an even number of Tms and that the first Tm, a signal peptide, is not cleaved off. Our study shows that SRS is suitable to test for protein membrane localization and possibly for more detailed topological analysis of membrane proteins.
