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

aimTo evaluate the use of analgesia for vaginal birth, in women with and without severe maternal morbidity (SMM) and to describe sociodemographic, clinical, and obstetric characteristics and maternal and perinatal outcomes associated with labor analgesia.

methodsSecondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health (WHO-MCS), a global cross-sectional study performed between May 2010 and December 2011 in 29 countries. Women who delivered vaginally and had an SMM were included in this analysis and were then divided into two groups: those who received and those who did not receive analgesia for labor/delivery. We further compared maternal characteristics and maternal and perinatal outcomes between these two groups.

resultsFrom 314,623 women originally included in WHO-MCS, 9,788 developed SMM and delivered vaginally, 601 (6.1%) with analgesia and 9,187 (93.9%) without analgesia. Women with SMM were more likely to receive analgesia than those who did not experience SMM. Global distribution of SMM was similar; however, the use of analgesia was less prevalent in Africa. Higher maternal education, previous cesarean section, and nulliparity were factors associated with analgesia use. Analgesia was not an independent factor associated with an increase of severe maternal outcome (Maternal Near Miss + Maternal Death).

conclusionsThe overall use of analgesia for vaginal delivery is low but women with SMM are more likely to receive analgesia during labor. Social conditions are closely linked with the likelihood of having analgesia during delivery and such a procedure is not associated with increased adverse maternal outcomes. Expanding the availability of analgesia in different levels of care should be a concern worldwide.
