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
backgroundSepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, being the primary cause of death from infection, especially if not recognized and treated promptly. The aim of this study was to analyze whether IL-6 rs1800795 polymorphism is associated with septic shock-related death in European white patients who underwent major surgery.
methodsWe performed a retrospective study on 202 septic shock patients who underwent major cardiac or abdominal surgery. The septic shock was established according to the international septic shock definition. The primary outcome variable was the death within 90 days after diagnosis of septic shock. The IL-6 rs1800795 polymorphism was genotyped by Sequenom's MassARRAY platform.
resultsThe median age of the patients was 73 years, 63.4% were male, and more than 40% of patients had heart disease and hypertension. Overall, the survival analysis showed that 111 (55%) patients died with a survival median of 39 days (95% CI 30.7; 47.2). The genetic analysis association with survival was performed under a recessive genetic model (CC vs. GG/CG). Patients with IL-6 rs1800795 CC genotype had higher mortality rate than the IL-6 rs1800795 GG/CG genotype at days 7 [31.6% (6/19) vs. 10.4% (19/183); log-rank test (p = 0.005)] and 28 [57.9% (11/19) vs. 33.3% (61/183); log-rank test (p = 0.009)], and 90 [68.4% (13/19) vs. 53.5% (98/183); log-rank test (p = 0.006)]. The IL-6 rs1800795 CC genotype was associated with higher risk of septic shock-related death during the first 7 days [adjusted hazard ratio (aHR 4.65; p = 0.002), 28 days (aHR 2.50; p = 0.006), and 90 days (aHR 2.28; p = 0.006)] with septic shock. When patients were stratified by type of surgery, those with IL-6 rs1800795 CC genotype who underwent cardiac surgery had higher risk of death during the first 7 days (aHR 18.39; p = 0.001) and 28 days (aHR 6.1; p = 0.025) than IL-6 rs1800795 GG/GC carrier, whereas patients with IL-6 rs1800795 CC genotype who underwent abdominal surgery had higher risk of death during all follow-up (aHR 1.98; p = 0.050) than IL-6 rs1800795 GG/GC carrier.
conclusionsThe presence of IL-6 rs1800795 CC genotype was associated with higher risk of septic shock-related death in patients who underwent major cardiac or abdominal surgery. These findings need robust validation in bigger independent cohorts.
