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

objectiveDoes TMJ nociception, as measured by a behavioral assay, differ during pregnancy, potentially due to the effect of sex steroids?

methodsThirty - two Sprague Dawlcy rats were randomly allocated to either mid- (EH 11) or late- (EH 17) pregnancy groups. The animals within each group were further allocated to a saline or CFA treatment. At EH 11 or EH 17, the animals were injected bilaterally into TMJ with either saline (15

resultsCFA injection resulted in the animals eating longer in both the mid - pregnant and late-pregnant groups. Plasma estradiol was higher in the late - pregnant group versus the mid - pregnant group. Importantly, the CFA injected late-pregnant group ate for a shorter amount of time (i. e., shorter meal rate) than the CFA injected rats at mid - pregnancy.

conclusionThe reduced nociceptive response (shorter meal rate) in the CFA injected late - pregnant group may be due to greater estradiol versus the CFA injected mid - pregnancy rats. Thus, one potential reason why women report fewer TMJ symptoms during pregnancy is the higher level of circulating estradiol.
