1 · What the graph read from it

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.

2 · The registry

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

MicroRNA (miR)‑126 is known to inhibit inflammatory responses in various inflammatory‑related diseases, but its role during the cerebral ischemia/reperfusion (I/R) injury remains unknown. The present study aimed to examine the interaction between miR‑126 and RAB3A interacting protein (RAB3IP), and explore its potential protective effects during I/R injury. The human neuroblastoma cell line SH‑SY5Y was cultured in an oxygen‑glucose deprivation/reoxygenation (OGD/R) environment to simulate I/R injury to assess miR‑126 expression and cell viability. SH‑SY5Y cells cultured in normal conditions were used as a negative control (NC) group. SH‑SY5Y cells were transfected with a miR‑126 mimic or an NC mimic, then cultured in OGD/R conditions; in rescue experiments, SH‑SY5Y cells were co‑transfected with RAB3IP overexpression or NC plasmid together with mimic‑NC or mimic‑miR, and then maintained in an OGD/R environment to evaluate miR‑126, RAB3IP expression, cell viability and apoptosis. Cell viability was reduced in the Model group compared with the NC group, suggesting the successful construction of the OGD/R model. miR‑126 expression was downregulated in the Model group compared with the NC group. However, following transfection with mimic‑miR, cell viability increased compared with the mimic‑NC group. Annexin V and PI staining and Hoechst/PI assays also indicated that apoptosis was reduced in the mimic‑miR group compared with the mimic‑NC group. RAB3IP expression was reduced following mimic‑miR transfection. In rescue experiments, miR‑126 negatively regulated RAB3IP expression; by contrast, RAB3IP did not affect that of miR‑126. In addition, RAB3IP overexpression attenuated the protective effect of miR‑126 on OGD/R‑induced apoptosis. These findings suggest that miR‑126 protects against cerebral I/R injury by targeting RAB3IP.
