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
Objective: Insulin-like growth factor 1 (IGF-1) protects neuronal-cell damage by ischemia. Although neuronal cells have been reported to produce IGF-1, the molecular mechanisms remains obscure. Dexmedetomidine (DEX) protects neuronal cells from ischemic damage. We investigated the involvement of IGF-1 in the effect of DEX pretreatment on neuronal ischemic damage using an Materials: We used Dexmedetomidine and cryopreserved passaged mouse hippocampal neuronal HT22. Other reagents in this study were analytical grade. Methods: Ischemia-reperfusion was modeled using the Results: OGD/R loading promoted LDH release from neuronal cells, while DEX pretreatment suppressed the LDH release. IGF-1 release from them was primed by DEX pretreatment under OGD/R condition, but not under normal conditions. Akt was activated in DEX-pretreated cells following OGD/R loading. IGF-1 neutralizing antibody ( Conclusions: Our results demonstrate that neuronal cells primed with DEX under OGD/R conditions could release IGF-1 and potentially protect themselves via the IGF-1/Akt pathway. Consequently, it appears that neuronal cells activated by DEX have the capacity to self-protect from ischemic damage.
