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

The selection of a stably expressed reference gene is a critical step for the quantitation of gene expression by qRT-PCR. We tested the stability of expression of nine putative reference genes in normoxia and hypoxia in four different human cell types: coronary (HCAECs) and pulmonary endothelial cells (HPAECs), EA.hy926 endothelial cells, and A549 alveolar epithelial cells. Cells were cultured in normoxic and hypoxic conditions for up to 72 h. Total RNA was isolated and used for qRT-PCR. Stability of expression was assessed by calculating the coefficient of variation of the cycle threshold (Ct CV) by pairwise comparison of ΔCt values, and by the NormFinder algorithm. A final rank was calculated for each gene. Finally, we analyzed
