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

backgroundLittle is known about severe maternal morbidity (SMM) among women with disabilities.

objectiveWe assessed differences in SMM and other perinatal complications by presence and type of disability. We hypothesised that SMM and other complications would be more common in births to women with disabilities than to women without disabilities.

methodsWe conducted a retrospective cohort study of California births from 2000 to 2012, using birth and death certificate data linked with hospital discharge data. We included singleton deliveries with gestational age of 23-42 weeks. We classified women as having any disability or not and identified disability type (physical, hearing, vision, intellectual/developmental disabilities [IDD]). Our primary outcome was a composite indicator of SMM. Secondary outcomes included additional perinatal complications: gestational hypertension, preeclampsia, gestational diabetes, venous thromboembolism, chorioamnionitis, puerperal endometritis and mental health disorders complicating pregnancy, childbirth or the puerperium. We used modified Poisson regression to obtain covariate-adjusted relative risks (RR) and 95% confidence intervals (CI) for the association of disability status and type with SMM and secondary outcomes.

resultsOf 5,787,090 deliveries, 33,044 (0.6%) were to women with disabilities. Of these, 311 per 10,000 were complicated by SMM, compared with 84 per 10,000 deliveries to women without disabilities. In multivariable analyses, risk of SMM for births to women with disabilities was nearly three times that for women without disabilities (RR 2.84, 95% CI 2.67, 3.02). Proportion and risk of SMM were greatest for vision disability (793 per 10,000; RR 4.04, 95% CI 3.41, 4.78). Secondary outcomes were also more common among women with disabilities. In particular, more than a third of births to women with IDD (37.4%) were complicated by mental health disorders (versus 2.2% for women without disabilities).

conclusionAs hypothesised, SMM and other perinatal complications were more common among women with disabilities than among women without disabilities.
