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
objectiveTo investigate and analyze the clinical efficacy and safety of polymyxin B sulfate in the treatment of carbapenem-resistant gram-negative bacteria (CR-GNB) in sepsis; in order to provide reference for the clinical diagnosis, treatment and prognosis evaluation of sepsis.
methodsThe clinical data of 76 patients with CR-GNB sepsis treated with polymyxin B sulfate combined with an anti-infection regimen in the First Affiliated Hospital of Gannan Medical University from January 2020 to February 2024 were retrospectively studied. To analyze and discuss the clinical characteristics, results of the bacterial culture and drug sensitivity, clinical efficacy and prognosis of CR-GNB patients, efficacy comparison of different doses of polymyxin B sulfate treatment regimens, efficacy comparison of different combination regimens based on polymyxin B sulfate, changes in clinical indexes before and after treatment of polymyxin B sulfate, adverse drug reactions and adverse events of polymyxin B sulfate were investigated.
resultsA total of 76 patients with CR-GNB sepsis were included in this study, with 55 males and 21 females, with an average age of 59.86 years old, 44 of which were (57.89%) were > 60 years old. All patients included in this study were treated with polymyxin B based combination therapy, 49 cases (64.47%) received the two-drug combination regimen, 27 cases (35.53%) received the three-drug or more combination regimen, and all the patients had the above treatment followed by systematic symptomatic supportive treatment. Patients in this study received polymyxin B for an average of (8.6±4.3) days, there were 60 (78.95%) patients with effective clinical treatment, and 49 patients (64.47%) achieved pathogen (bacterial) clearance of infection. Twenty-two cases (28.95%) died within 28 days, 31 cases (40.79%) died within 90 days, and the remaining 23 cases (30.26%) survived. There were statistically significant differences in the therapeutic effective rates and bacterial clearance rates among different courses of treatment or different initial doses of polymyxin B (all
conclusionA Polymyxin B sulfate based combination regimen is an effective choice for CR-GNB sepsis, which can maximize the survival and prognosis benefits of sepsis patients.
