Maternal pulmonary edema after 46 h of ritodrine hydrochloride administration: A case report.
Article in Case reports in women's health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
introductionRitodrine hydrochloride is still widely used as a tocolytic agent in Japan, but it can cause maternal pulmonary edema, which may paradoxically induce preterm birth. Here we present a case of severe pulmonary edema due to <48 h of ritodrine administration. CASE: A 46-year-old woman was diagnosed with threatened preterm labor (TPL) and placenta previa at 26 weeks of gestation. She had mild uterine contractions and genital bleeding. Ritodrine hydrochloride, magnesium sulfate, and betamethasone were administered. She developed dyspnea 46 h after starting ritodrine administration. Chest X-ray showed pulmonary edema. Even after cessation of ritodrine, dyspnea did not lessen and there were regular uterine contractions with abdominal pain. Emergency caesarean section was performed. A female neonate was delivered and admitted to the neonatal intensive care unit. After surgery, maternal dyspnea decreased without any complications. DISCUSSION: Excessive use of ritodrine or its use in combination with other tocolytic agents can cause maternal pulmonary edema, even with <48 h of use. Adverse maternal side-effects and rebound uterine contractions due to cessation of ritodrine may paradoxically trigger preterm birth. Strict patient selection for tocolytic therapy is essential and ritodrine requires caution because of its potential side-effects.
