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

This prospective cohort study compared the associations between office blood pressure (OBP) and home blood pressure (HBP) measured before 20 weeks of gestation with the subsequent development of placenta-mediated pregnancy complications (PMPCs). A total of 975 pregnant women were included in the study. OBP and HBP were measured between 10 weeks 0 days and 19 weeks 6 days of gestation, using HBP values from the same gestational weeks as OBP. When both OBP and HBP were included simultaneously in a binary logistic regression model, per 1 standard deviation increase, the adjusted odds ratios (aORs) for office and home systolic blood pressure (SBP) were 1.16 (95% confidence interval [CI]: 0.95-1.42) and 1.68 (95% CI: 1.36-2.09), respectively. For diastolic blood pressure (DBP), the aORs were 1.36 (95% CI: 1.10-1.69) for office and 1.70 (95% CI: 1.37-2.12) for home measurements. The likelihood ratio test showed that adding home SBP to a model with office SBP improved model fit (P value < 0.0001), whereas adding office SBP to a model with home SBP did not (P value = 0.2). For DBP, adding either home or office values improved model fit (P value < 0.0001 and P value = 0.005, respectively). Home SBP was more strongly associated with PMPCs than office SBP. Although home DBP was not statistically stronger than office DBP, its effect estimate was higher. These findings support the added value of HBP monitoring during pregnancy for predicting PMPCs.
