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
purposeActive metabolites of arachidonic acid (AA), eicosanoids, are exerting a significant influence on renal homeostasis. In our recent paper, we demonstrated that high levels of lipoxygenase (LOX)-derived AA metabolites, hydroxyeicosatetraenoic acids (HETEs), unfavorably influence post-transplant function of kidney allografts. Hence, in this study, we wanted (1) to analyze 5-, 12- and 15-HETE levels in non-diabetic chronic kidney disease (CKD) patients, already undergoing regular hemodialysis treatment, and determine factors that may influence these eicosanoids' generation, as well as, (2) to verify whether application of glucose-containing, instead of glucose-free, dialyzing fluids may be beneficial for the limitation of 5-, 12- and 15-HETE synthesis during a single hemodialysis session.
methodsTwenty-four healthy individuals and 50 CKD patients undergoing regular hemodialysis treatment were included in the study. CKD patients were divided into two subgroups depending on presence/absence of glucose in dialyzing fluid. LOX-derived HETEs were measured using liquid chromatography.
resultsResults demonstrated higher levels of examined eicosanoids in CKD patients (P<0.05 for all). Older age and higher C-reactive protein levels were associated with HETEs concentrations. Presence of glucose in dialyzing fluid significantly diminished the increase in 5- and 12-HETE synthesis (411.24% vs. 107.29%, P<0.006; 301.70% vs. 98.21%, P<0.0008, respectively), however, it did not influence 15-HETE generation (156.98% vs. 135.24%, P=0.26).
conclusionsNon-diabetic CKD patients have higher levels of LOX-derived HETEs, which are associated mainly with age and intensified inflammatory process. The presence of glucose in the dialysate is associated with a reduced synthesis of selected LOX-derived HETEs in these patients; hence, we speculate that the application of such a simple hemodialysis fluid modification may have a favorable influence on post-transplant outcomes.
