Relationship between the Clinical Course of Ulcerative Colitis during Pregnancy and the Outcomes of Pregnancy: A Retrospective Evaluation.

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
Objective Little information is available on the relationship between the clinical course of ulcerative colitis (UC) and the outcomes of pregnancy and delivery in pregnant Japanese women. The aim of this retrospective study was to determine the factors that influence pregnancy and childbirth in middle-aged UC patients. Methods We studied 53 pregnancies in 45 pregnant women with UC who delivered at our department. They included 41 pregnancies that started while in UC remission and 12 pregnancies that started in the UC active phase. The following factors were evaluated: 1) the clinical course of UC; 2) the frequency and details of abnormal pregnancy/abnormal delivery; and 3) the course of pregnancy/delivery. We compared the clinical features, course of UC, and details of treatment between women with a normal pregnancy/delivery and those with an abnormal delivery. Results A comparison of the remission and acute groups showed lower clinical activity indices (CAIs) during pregnancy in the remission group and significantly higher rates of recurrence/exacerbation in the active group (75%) than in the remission group (7.3%). The respective CAIs in the first, second, and third trimesters were 3 and 6, 3 and 5, and 3 and 4, in the remission and active groups, respectively. Live infants were delivered in 51 (96%) pregnancies, with 7 (17%) abnormal pregnancies in the remission group and 4 (33.3%) in the active group (p>0.05). Abnormal delivery occurred in 16 of 53 (30.1%) pregnancies, and the rate was higher in the remission group than in the active group (p>0.05). In both groups, the most common abnormal event during pregnancy was delivery of low-birth-weight infants. Delivery was normal in 37 cases and abnormal in 16 cases. A multivariate analysis showed that a shorter UC disease duration (odds ratio=1.16) and higher CAI in the first trimester (odds ratio=1.49) were associated with an increased risk of abnormal pregnancy. Conclusion Our findings demonstrated that the clinical course of UC, as evaluated by the CAI, during pregnancy influenced the outcome of pregnancy and delivery.
