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
backgroundBacterial meningitis remains a significant global health concern, particularly in resource-limited settings where patients often present late and have co-existing conditions. This study aimed to identify the common bacterial pathogens causing meningitis, assess their antibiotic resistance profiles, and evaluate treatment outcomes in suspected meningitis patients.
methodsWe conducted a prospective cross-sectional study involving 195 patients suspected of meningitis at the University of Gondar Comprehensive Specialized Hospital. Cerebrospinal fluid samples were collected and analyzed using both culture and PCR for bacterial etiology. Antimicrobial susceptibility was determined via the disc diffusion method. Treatment outcomes were evaluated using the Glasgow Outcome Scale. We used descriptive statistics, bivariate analysis, and multivariable analysis to identify factors associated with unfavorable patient outcomes, with statistical significance set at a p-value < 0.05 at a 95% confidence level.
resultsThe prevalence of bacterial meningitis, confirmed by either culture or PCR, was 28.2% (55/195). Among the 55 detected bacterial etiologies, E. coli was the most common (45.5%, n = 25), followed by H. influenzae (16.4%, n = 9), S. pneumoniae (10.9%, n = 6), N. meningitidis (7.3%, n = 4), S. aureus (5.5%, n = 3), S. agalactiae (5.5%, n = 3), K. pneumoniae (1.7%, n = 1), L. monocytogenes (1.7%, n = 1), and mixed infections of E. coli and K. pneumoniae (5.5%, n = 3). Notably, only 7.2% (14/195) of bacteria were recovered by culture, with S. pneumoniae and K. pneumoniae (4 each) being the most frequently cultured etiologies, followed by E. coli and S. aureus (2 each). Among K. pneumoniae isolates, 75% (3/4) were resistant to trimethoprim-sulfamethoxazole, and 50% (2/4) to meropenem, cefotaxime, and ciprofloxacin. One of four (25%) S. pneumoniae isolates showed resistance to erythromycin, trimethoprim-sulfamethoxazole, ciprofloxacin, and rifampin. Overall, 13.8% (27/195) of study participants experienced unfavorable outcomes. Factors independently associated with unfavorable outcomes included a low Glasgow Coma Scale (AOR = 0.668, 95% CI = 0.529-0.845), comorbidity (AOR = 9.221, 95% CI = 1.580-53.815), and delayed presentation (AOR = 1.684, 95% CI = 1.206-2.352).
conclusionsPCR significantly outperformed culture in detecting bacterial pathogens. E. coli was the most common causative agent of bacterial meningitis, and we observed high rates of antibiotic resistance among Gram-negative bacteria. While most patients had favorable outcomes, low Glasgow Coma Scale scores, comorbidities, and delayed presentation to healthcare facilities were independently associated with unfavorable outcomes.
