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 examine the association between third trimester cervical length (CL) measurement and duration of the first stage of labor.

methodsThis prospective cohort study included women with a singleton pregnancy who had routine CL measurements taken by transvaginal ultrasonography between 37 and 39 weeks gestation. Subjective duration of the first stage of labor was defined as the duration of contractions that the women subjectively had from the onset of regular contractions to full effacement of the cervix. Objective duration of first stage of labor was defined as 3 cm cervical dilation independent of cervical effacement until full effacement of the cervix. Associations between variables were analyzed using nonparametric correlations coefficients. A model relating the duration of labor to predictors was built using linear regression.

resultsIn this analysis a total of 129 women were included. There was no significant correlation between CL and subjective duration of labor (ρ = -0.037, p = 0.695); however, a reduction in CL increased the objective duration of the first stage of labor (ρ = -0.269, p = 0.013). In univariate analysis parity (p = 0.018), hypertensive disorders (p = 0.013) and induction of labor (p = 0.022) were significantly associated with subjective duration of the first stage of labor.

conclusionA long cervix in the third trimester is not associated with a prolonged first stage of labor. Induction of labor and multiparity were associated with a shorter first stage of labor while hypertension was associated with a longer duration of labor.
