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

objectiveTo determine the mechanism by which hypoxia increases expression of iNOS in human normal peritoneal and adhesion fibroblasts.

designProspective experimental study.

settingUniversity medical center. PATIENT(S): Primary cultures of fibroblasts from normal peritoneum and adhesion tissues. INTERVENTION(S): Hypoxia-treated cells. MAIN OUTCOME MEASURE(S): We used real-time reverse transcription-polymerase chain reaction to quantify mRNA levels of iNOS and nuclear factor kappa B (NF-kappaB). Western blots were used to determine iNOS, NF-kappaB, IkappaB-alpha, and phospho-IkappaB expression levels in normal peritoneal and adhesion fibroblasts in response to hypoxia. RESULT(S): Hypoxia resulted in a significant increase in iNOS and NF-kappaB expression in normal and adhesion fibroblasts. Furthermore, both cell types manifested lower levels of NF-kappaB, cytoplasmic phospho-IkappaB-alpha, and iNOS proteins. In contrast, they manifested higher levels of cytoplasmic IkappaB-alpha and IkappaB-alpha/NF-kappaB ratios as well as a phosphorylated-IkappaB-alpha/NF-kappaB ratio. Under hypoxic conditions, both cell types exhibited significantly decreased cytoplasmic NF-kappaB, IkappaB-alpha levels, and significantly increased cytoplasmic phospho-IkappaB-alpha, iNOS, and NF-kappaB protein levels. CONCLUSION(S): Hypoxia increases iNOS expression by a mechanism involving activation of NF-kappaB. The ratio of IkappaB-alpha/NF-kappaB or IkappaB-alpha/p-IkappaB-alpha can be used to monitor activation.
