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
This study examined the effect of integrin cytoplasmic domain-associated protein 1α (ICAP-1α) and its mutatants T38A and I138A on the adhesion, migration and tube formation of 2H-11 cells. rAAV-ICAP-1α, rAAV-T38A and rAAV-I138A were constructed. After infection, the expression of ICAP-1α and p-ERK1/2, p-c-Jun protein was measured by Western blotting. Adhesion ability was evaluated by using MTT. Cell migration was determined by using Boyden chamber method. Tube formation test was conducted on Matrigel. The results showed that in ICAP-1α, T38A and I138A groups, ICAP-1α protein expression was increased. In T38A and I138A groups, phospho-ERK1/2, phospho-c-Jun protein expressions were significantly increased as compared with the control group and the GFP group. ICAP-1α group protein expression was obviously decreased when compared with the control group and the GFP group. Cell adhesion ratio was 0.1429±0.0080 in control group, 0.1434±0.0077 in GFP group and the ratio in T38A and I138A groups increased to 0.3210±0.0082 and 0.3250±0.0079, respectively. In ICAP-1α group, the ratio was decreased to 0.1005±0.0073. In T38A and I138A groups, the number of migrating 2H-11 cells was increased to 31.45±3.20 and 33.10±5.40 against 18.51±2.80 in control group and 20.47±3.12 in GFP group. In ICAP-1α group, the number was decreased to 12.06±1.72. The number of tube-like structures was increased to 20.41±2.54 in T38A and to 22.26±3.07 in I138A groups as compared to those of control group 12.45±1.84 and GFP group 13.63±2.71. In ICAP-1α group, the number of tube-like structures was decreased to 8.32±1.24. It was suggested that rAAV-T38A and rAAV-I138A transfection can substantially increase 2H-11 cell adhesion, migration and angiogenisis, while rAAV-ICAP-1α can greatly inhibit the effect. These effects might be correlated with ERK1/2 and c-Jun protein phosphorylation.
