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
The urine pregnancy test is one of the most useful methods for initially excluding pregnancy emergencies in the emergency department (ED). Although most urine pregnancy tests are regarded to be up to 99% accurate, false-negative results may lead ED physicians toward considering incorrect diagnoses, mask critical conditions, and even influence patient safety. Therefore, blood pregnancy tests (quantitative measurements) are clinically used for second-line screening. A double false-negative result from two pregnancy tests is very rare and has scarcely been reported for life-threatening ruptured ectopic pregnancy patients. In this report, for the first time, we describe a rare case of a 32-year-old female who suffered a life-threatening ruptured ectopic pregnancy and who had a double pregnancy test (both urine and blood) that was a false negative.
