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
objectiveWe aimed to investigate the impact of our institutional sepsis protocol on the empirical treatment of carbapenem-resistant Gram-negative bacteria in a setting where infectious disease consultation (ID) is available 7 days / 24 h and broad-spectrum antibiotic use requires ID approval.
methodsA total of 612 patients (168 patients pre-guideline, 444 patients post-guideline) who received empirical antibiotics for suspicion of sepsis before documentation of antibacterial susceptibility were included. Demographic, clinical and microbiological data were collected from the hospital's electronic medical record system, retrospectively. Compliance with institutional guidelines and the rate of appropriate antibiotic use prior to the availability of antibiograms were assessed.
resultsThere was a statistically significant increase in the utilization rate of empirical antibacterial treatment based on pre-defined risk factors of multidrug resistance [OR (95% CI) 1.73 (1.21-2.48), p = 0.003]. Furthermore, appropriateness of the initial antibacterial treatment according to the antibiogram results increased significantly in the post-guideline period [OR (95% CI) = 3.25 (2.09-5.06), p < 0.001]. The rate of compliance with guideline recommendations (p = 0.004) and the rate of appropriate empirical antibiotic treatment (p < 0.001) by each year were significant when compared with the pre-guideline period. Also, practices that improve drug pharmacokinetics such as loading dose, prolonged infusion of meropenem and adjusting antibiotic doses according to renal function increased statistically after the release of guideline.
conclusionAn institutional sepsis protocol based on risk factors for multidrug resistance and local epidemiology increased the rate of appropriate empirical antibiotic treatment even in a setting where ID consultation is readily available.
