Analysis of clinical prognosis in patients with non-hepatic hyperammonemia.
Observational study in Medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
abstractThe aim of this study was to evaluate the association of non-hepatic hyperammonemia (NHH) with the prognosis of critically ill patients with NHH.According to the serum ammonia level, the patients with NHH (n = 498) were retrieved by us. The risk factors of the mortality with NHH patients were investigated by conducting univariate and multivariate logistic regression analyses. A nomogram to predict the risk of hospital mortality was constructed. Receiver operating characteristic curve (ROC) analysis was conducted to compare nomogram (ammonia into a prognostic model, P1) with the simplified acute physiology II (SAPSII) and quick sequential organ failure assessment (qSOFA).Five independent factors for the mortality in patients with NHH were identified, including age, platelets, bun, hemoglobin, and ammonia. Models P1 using ammonia showed good prediction power. The AUROC of P1 (AUROC, 0.755 [95% CI, 0.713-0.796]) was higher than that of qSOFA (AUROC, 0.500 [95% CI, 0.449-0.551]), and SAPS II (AUROC, 0.703[95% CI, 0.658-0.748]).Ammonia was an independent prognostic predictor of mortality for NHH patients. We developed a nomogram that can predict hospital mortality with patients. Nomogram had superior discriminative power to qSOFA and SAPS II, indicating that the nomogram may have clinical utility.
