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

purposeTo investigate the association of ovarian hyperstimulation syndrome (OHSS) and adverse maternal and neonatal outcomes.

methodsThis retrospective study used combined Korea National Health Insurance (KNHI) claims and National Health Screening Program for Infants and Children data. Women who gave birth through in vitro fertilization using fresh embryo transfer during 2017-2022 were enrolled. Z-scores were calculated. Student's t-test, analysis of variance, Pearson's chi-squared (χ

resultsThe non-OHSS group included 27,337 women, while the OHSS group included 1,570 women (mild to moderate, 1,308; severe, 262). The OHSS group was significantly younger (34.86 ± 3.54 vs. 36.21 ± 3.58 years, p < 0.0001) and had significantly higher rates of primiparity, cesarean section, and polycystic ovary syndrome (88.98% vs. 82.89%, p < 0.0001; 75.8% vs. 65.75%, p < 0.0001; and 29.24% vs. 14.37%, p < 0.0001, respectively). OHSS was associated with a decreased incidence of low birth weight and with an increased incidence of macrosomia (adjusted odds ratio [95% confidence interval], 0.53 [0.38-0.72], p < 0.0001; and 1.83 [1.42-2.35], p < 0.0001). OHSS was associated with an increased incidence of transient tachypnea of the newborn (TTN) and respiratory distress syndrome (RDS) (1.32 [1.02-1.71], p = 0.03; and 1.57 [1.30-1.91], p < 0.0001).

conclusionOHSS is associated with a decreased incidence of low birth weight and an increased incidence of macrosomia, TTN, and RDS.
