Factors associated with a maternal lower-limb neurological deficit after vaginal delivery.

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
introductionThe etiology of lower-limb neurological deficit after vaginal delivery remains poorly understood. The objective herein was to identify factors associated with this maternal nerve injury after vaginal delivery. MATERIAL AND
methodsA single-center, case-control (matching 1:4) study. Cases were women with a lower-limb neurological deficit that appeared immediately after vaginal delivery. Controls were randomly selected women who gave birth vaginally during the same period, without any deficit. Finally, to assess the rates of factors associated with these deficits, we studied them using a randomly selected 5% sample of the population with vaginal deliveries.
resultsDuring the 30-month study period, 31 cases were identified among 10 333 women who gave birth vaginally (0.3%, 95% CI 0.20-0.43); 124 controls were also included. After logistic regression, the presence of a neurological deficit after delivery was associated with second-stage labor duration (per hour odds ratio [OR] 3.67, 95% CI 2.09-6.44; OR per standard deviation increase 2.73, 95% CI 1.75-4.25, p < 0.001) and instrumental delivery (OR = 3.24, 95% CI 1.29-8.14, p = 0.012), with no interaction effect (p = 0.56). Extrapolation of these factors to a 5% sample of the overall population of women with vaginal births showed that the rate of these deficits would be very low for women with second-stage labor lasting up to 90 min without instrumental delivery (0.05%) but increased to 1.52% when these factors were combined (OR 33.1, 95% CI 9.4-116.9).
conclusionsFollowing vaginal delivery, the onset of a neurological deficit is principally associated with the duration of second-stage labor and instrumental delivery.
