Predictive value of ScvO
Article in Herz, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe examined the predictive value of central venous oxygen saturation (ScvO2) changes regarding the occurrence of pericardial tamponade following cardiac surgery.
methodsWe retrospectively identified 66 consecutive patients in whom ScvO2 and arterial lactate levels were analyzed during an 8‑h time interval preceding pericardiotomy due to pericardial tamponade (PT), and at equivalent time points in 30 control patients (C) who had an uncomplicated course.
resultsThe median age of the patients was 74 years (interquartile range, 63-78). Three percent of procedures were re-operations. There were no differences between the baseline values of PT and C patients. Pericardiotomy was performed on average 1 day (0-3.5) after cardiac surgery. PT patients displayed a significant decline (p < 0.001) to lower ScvO2 levels (p < 0.001) and a significant increase (p = 0.005) to higher arterial lactate levels (p = 0.019) during the 8 h preceding pericardiotomy, whereas C patients did not (p = 0.440 and p = 0.279, respectively). PT was associated with a longer hospital stay (p = 0.04) and a higher in-hospital mortality (p = 0.008). An ScvO2 decline below 60% (p = 0.018), a delta ScvO2 decline greater than 5% (p = 0.001), and a delta lactate increase greater than 0.18 mmol/l (p = 0.002) during the 8 h preceding pericardiotomy were independently associated with PT. None of these parameters predicted in-hospital mortality.
conclusionDeteriorations in ScvO2 might serve as an early marker of PT following cardiac surgery.
