Use of a Visual Aid in addition to a Collector Bag to Evaluate Postpartum Blood loss: A Prospective Simulation Study.
Article in Scientific reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
Postpartum hemorrhage (PPH) is one of the most common causes of mortality in obstetrics worldwide. The accuracy of estimated blood loss is a priority in determining appropriate treatment. Will the additional use of a visual aid improve physicians' accuracy in estimating blood loss compared to the use of a collector bag and baby scale alone? Simulation training sessions created three vaginal delivery scenarios for participants to estimate volumes of blood loss: firstly, using only a collector bag and a baby weight scale and secondly, adding a visual aid depicting known volumes of blood. The primary endpoint was to determine if participants could accurately evaluate blood loss within a 20% error margin. The addition of the visual estimator resulted in overestimation of blood loss. The rates of participants' estimations were significantly more accurate when using the collector bag with the baby weight scale without the addition of the visual aid; 85.5% versus 33.3% (p < 0.01) for 350 mL, 88.4% versus 50.7% (p < 0.01) for 1100 mL and 88.4% versus 78.3% (p < 0.01) for 2500 mL, respectively. Additional use of a visual aid with a collector bag does not seem to be useful in improving the accuracy in the estimation of blood loss.
