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

introductionRates of delivery by cesarean section have gradually risen in many parts of the world, and it is regarded as a safe surgical procedure with expanded indications. We assessed maternal complications within 6 weeks postpartum after planned cesarean section and after planned vaginal delivery among patients without medical indication for cesarean section. MATERIAL AND

methodsThis was a retrospective cohort study based on Swedish national registers and included 714 326 deliveries from 2008 to 2017. The study group consisted of cephalic, singleton, term pregnancies and excluded those with previous cesarean or pregnancy conditions that would qualify for cesarean section. We compared the risks of short-term complications between planned cesarean section and planned vaginal delivery. We obtained adjusted risk ratios (ARRs) using modified Poisson regression models adjusting for maternal age, parity, body mass index, smoking, country of birth, and county.

resultsThe outcomes studied were infections and thromboembolism. In the planned cesarean section group (n = 22 855), 15% had a postpartum infection compared with 10% in the planned vaginal group (n = 691 471) (ARR 1.6; 95% confidence interval [CI] 1.5-1.6), and 0.08% vs 0.05% had a postpartum pulmonary embolism (ARR 1.7; 95% CI 1.0-2.6). The obtained risk estimates corresponded to "number needed to harm" estimates of 17 and 3448, respectively. When dividing the infections into subgroups, the risk of endometritis (ARR 1.2; 95% CI 1.1-1.3), wound infection (ARR 2.7; 95% CI 2.4-3.0), urinary tract infection (ARR 1.5; 95% CI 1.3-1.7), and mastitis (ARR 2.0; 1.9-2.2) was higher after planned cesarean section.

conclusionsAmong patients without medical indication for planned cesarean section, the risks of short-term maternal complications were higher with planned cesarean section than with planned vaginal delivery.
