Women with Rheumatoid Arthritis have similar rates of postpartum maternal outcomes compared to women without autoimmune disease.
Article in Seminars in arthritis and rheumatism, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectiveLimited data exist on the effect of rheumatoid arthritis (RA) on maternal postpartum outcomes. Using a real-world, electronic health record (EHR) cohort, we assessed maternal postpartum outcomes in RA.
methodsIn a large, de-identified EHR, we identified possible RA deliveries using ≥1 delivery ICD-9 or ICD-10-CM codes and a validated RA algorithm. RA cases were required to be diagnosed by a rheumatologist on chart review. Maternal postpartum outcomes included rates of blood transfusion, rates of infection up to 6 weeks postpartum defined by a clinician, and length of hospital stay. We also identified deliveries to women without autoimmune diseases.
resultsWe identified 202 deliveries occurring after RA diagnosis and 596 deliveries to controls without autoimmune diseases. Postpartum infection rates were similar among RA patients and controls (8% vs. 4%, p = 0.10), as were red blood cell transfusion rates (2% vs. 2%, p = 1.00). RA case status was not significantly associated with postpartum infection (OR = 2.10, 95% CI 0.88 - 4.98, p = 0.09) but was significantly associated with preterm birth (OR = 2.11, 95% CI 1.38 - 3.23, p = 0.001). Corticosteroid use during pregnancy was common at 41%, while tumor necrosis factor inhibitor use was 13%. After adjusting for age at delivery and race, corticosteroid use at delivery was not associated with postpartum maternal infections but was associated with a significantly lower birthweight in RA cases.
conclusionWomen with RA have an increased risk of adverse pregnancy outcomes, particularly preterm birth. Our study highlights, however, that maternal postpartum outcomes such as postpartum infection and blood transfusion are not significantly increased in RA patients.
