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

Postpartum venous thromboembolism (VTE) is a serious complication, and electrolytes may play a role in coagulation homeostasis, but their associations with postpartum VTE remain unclear. A total of 25,792 pregnant women from Chinese multicenter cohort between January 2017 and December 2024 were included, and the occurrences of postpartum VTE within 6 weeks after delivery were followed. Here, we show that dysregulated perinatal electrolyte profiles and a reduced serum calcium (Ca) /potassium (K) ratio are novel and independent risk factors for postpartum VTE, with hemoglobin and D-dimer levels mediating such associations. Restricted cubic spline analyses showed that low serum Ca (overall association
