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

purposeSystemic lupus erythematosus (SLE) is a prominent autoimmune disease highly linked to adverse pregnancy outcomes (APOs). Previous research on the risk factors for APOs in SLE pregnancies has been limited by regional constraints or inadequate sample sizes. Comprehensive systematic reviews on this topic remain scarce. To address these research gaps, we conducted a rigorous meta-analysis and systematic review to elucidate the risk factors for APOs in SLE pregnancies.

methodsPubMed, Embase, Web of Science, and the Cochrane Library systematically searched for articles on risk factors for APOs in SLE pregnancy from initiation to March 25, 2025. Pooled odds ratios (ORs) were calculated using fixed-effect or random-effects models based on heterogeneity (I

resultsA total of 43 studies were reviewed. Patients with hypertension, lupus nephritis (LN), high disease activity, low complements, and antiphospholipid syndrome (APS)/positive antiphospholipid antibodies (aPL) were identified as having a higher risk for adverse pregnancy outcomes (APOs). Risk factors for preterm birth included LN, hypertension, disease flares, high disease activity, and APS/aPL. Risk factors for pregnancy loss included APS/aPL, low complements, disease flares, LN, hypertension, thrombocytopenia, and high disease activity. LN was also associated with an increased risk of intrauterine growth restriction and low birth weight.

conclusionsThis study identified risk factors for APOs in SLE pregnancies. These findings may support early identification of high-risk patients and guide timely interventions to improve maternal and fetal outcomes.
