Prenatal nicotine exposure alters postnatal cardiorespiratory integration in young male but not female rats.
Article in Experimental neurology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
The present study tested the hypothesis that prenatal nicotine exposure (PNE) induces sex specific alternations in indices of cardiorespiratory coupling during early development. Rat pups exposed to either nicotine (6 mg/kg/day) or saline (control) in utero were chronically instrumented with ECG electrodes for measurement of heart rate (HR) and respiratory frequency (RF) was monitored by whole body plethysmography on postnatal days (P)13, P16 and P26. PNE had no identifiable effect on resting respiratory frequency (RF) in either sex. There was however a strong trend (p=0.057) for resting HR to be elevated by PNE in male offspring only. Alternatively, the HR response to hypoxia (10% O(2)), was significantly blunted at P13 but significantly elevated at P26 s in the absence of any significant change in RF in PNE males only. Indicators of respiratory sinus arrhythmia (RSA) were also significantly reduced in P26 PNE males. No significant effects of PNE on HR, RF or RSA were identified in female offspring at any age. Our results demonstrate that PNE induces very specific changes in cardiorespiratory integration at select postnatal ages and these changes are more prominent in males. Additionally, alternations in cardiorespiratory integration appear to persist into later development in males only, potentially increasing the risk for cardiovascular diseases such as hypertension later in life.
