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

objectiveThis study sought to compare the efficacy and outcomes of fetal intracardiac intraventricular and interventricular septal potassium chloride (KCl) injections during the induced fetal demise process in a cohort of pregnant women with severe fetal abnormality who opted for late termination of pregnancy (TOP). MATERIALS AND

methodsThis study consisted of 158 pregnant women who requested late TOP for severe fetal abnormality between 22 and 36 weeks of pregnancy. Participants were randomly assigned with the simple randomization procedure to one of two feticide procedure groups: the intraventricular KCl injection group and the interventricular septal KCl administration group. We studied the clinical outcomes of both the feticide procedures.

resultsThe median total dose of strong KCl was significantly lower in the interventricular septal KCl administration group (3 mL) than in the intraventricular KCl injection group (5 mL, p < 0.001). The median time to reach asystole and the median total duration of the procedure was significantly shorter in the interventricular septal KCl administration group (42 s and 85 s, respectively) than in the intraventricular KCl injection group (115 s and 150 s, respectively, p < 0.001). We detected a statistically significant correlation between the gestational week at feticide and the total dose of KCl (r = 0.705, p < 0.001), time to reach asystole (r = 0.653, p < 0.001), and total duration of the procedure (r = 0.683, p < 0.001).

conclusionKCl administered directly into the interventricular septum induces immediate and permanent fetal cardiac asystole with a 100% of success rate without comprising maternal safety. We did not observe any maternal complications related to the procedure in our cases. Since the consequences of failed feticide procedure are challenging for both parents and healthcare providers, and providers are also concerned about potential legal implications regarding an unintended live birth, it is crucial to guide a strict protocol to confirm permanent fetal cardiac asystole.
