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

Previous studies using genetic mouse models have implicated COX-2 in the browning of white adipose tissues (WATs) in mice during cold exposure. However, COX-2 is important during development, and conventional knockouts (KOs) exhibit many defects, conditioned by genetic background. Similarly, the physiological relevance of transgenic overexpression of COX-2 is questionable. In the present study, we utilized mice in which COX-2 was deleted postnatally, bypassing the consequences of enzyme deficiency during development. Despite activation of thermogenesis and browning of inguinal WAT, cold exposure failed to increase COX-2 expression in the adipose tissues of mice with different genetic backgrounds, and the body temperature response to cold was unaltered in postnatal global COX-2 KOs. Selective disruption of COX-2 in adipose tissues also failed detectably to impact systemic prostaglandin biosynthesis. Browning of inguinal WATs induced by exposure to cold is independent of adipose tissue COX-2.
