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

objectiveWe aimed to assess the effectiveness of hydroxychloroquine (HCQ) in preventing hypertensive pregnancy disorders (HPD) among women with recurrent spontaneous abortion (RSA). STUDY

designThis retrospective cohort study included 462 pregnant women with RSA. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were used to balance baseline characteristics between HCQ and non-HCQ groups. The primary outcome comprised a composite of HPD, including preeclampsia, eclampsia, and gestational hypertension. Secondary outcomes included maternal complications and neonatal outcomes.

resultsHCQ was associated with a 62% decreased risk of HPD compared to no HCQ (weighted hazard ratio 0.38, 95% CI 0.16-0.94, P < 0.001). The cumulative incidence of HPD at 34 weeks was lower among HCQ users (5% vs 14%, P = 0.03). HCQ demonstrated greater efficacy in preventing HPD among women aged < 35 years, a body mass index (BMI) of ≥ 28, non-in vitro fertilization (IVF) pregnancies, and fewer than three prior miscarriages (P-interaction < 0.05). Notably, the risk of HPD was significantly lowered by 56 and 53% in combined HCQ and aspirin with/without low-molecular-weight heparin (LMWH) group compared with no HCQ counterpart, respectively.

conclusionsHCQ demonstrated promising efficacy in reducing HPD, particularly when used in conjunction with aspirin and/or LMWH therapy.
