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
An important criterion for effective gene therapy is sufficient chromosomal integration activity. The Sleeping Beauty (SB) transposon system is a plasmid system allowing efficient insertion of transgenes into the host genome. However, such efficient insertion occurs only after the system is delivered to nuclei. Since transposons do not have the transducing abilities of viral vectors, efficient delivery of this system first into cells and then into cell nuclei is still a challenge. Here, a phage display technique using a major coat displayed phage library is employed to identify a peptide (VTAMEPGQ) that can home to rat mesenchymal stem cells (rMSCs). A nanoparticle, called liposome protamine/DNA lipoplex (LPD), is electrostatically assembled from cationic liposomes and an anionic complex of protamine, DNA and targeting peptides. Various peptides are enveloped inside the LPD to improve its targeting capability for rMSCs and nuclei. The rMSC-targeting peptide and nuclear localization signal (NLS) peptide can execute the synergetic effect to promote transfection action of LPD. The homing peptide directs the LPD to target the MSCs, whereas the NLS peptide directs transposon to accumulate into nuclei once LPD is internalized inside the cells, leading to increased gene expression. This suggests that rMSC-targeting peptide and NLS peptide within LPD can target to rMSCs and then guide transposon into nuclei. After entering the nuclei, SB transposon increase the insertion rates into cellular chromosomes. The targeting LPD does not show obvious cell toxicity and influence on the differentiation potential of rMSCs. Therefore, the integration of SB transposon and LPD system is a promising nonviral gene delivery vector in stem cell therapy.
