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
introductionCeftazidime-avibactam (CAZ-AVI) has emerged as a promising treatment option for Gram-negative infections, particularly those caused by CAZ-Non-Susceptible (NS) pathogens. This systematic review and meta-analysis aim to assess the efficacy and safety of CAZ-AVI in these challenging infections.
methodsWe systematically queried EMBASE, Cochrane CENTRAL, and PubMed/Medline for studies published until September 15, 2024. Randomized Controlled Trials (RCTs) evaluating CAZ-AVI against Gram-negative infections were included. A meta-analysis was performed to calculate pooled odds ratios (OR) for both clinical and microbiological success.
resultsA total of 146 studies were identified through database searches, leading to the inclusion of 17 studies. Among the efficacy studies for Gram-negative pathogens, there was no significant difference in clinical success rates for CAZ-AVI compared to comparators (pooled OR: 0.90, p = 0.22), and a non-significant increase in microbiological success was observed (pooled OR: 1.20, p = 0.41). In contrast, for CAZ-NS pathogens, six studies reported no significant difference in clinical cure rates (pooled OR: 0.77, p = 0.24), while four studies indicated a non-significant increase in microbiological cure rates (pooled OR: 1.83, p < 0.02).
conclusionsThis study suggests that CAZ-AVI is a viable option for treating Gram-negative infections, including CAZ-NS pathogens. While it has shown promising activity against these resistant pathogens, its clinical and microbiological success rates are comparable to other antibiotics in the overall analysis. However, CAZ-AVI may offer an advantage in managing resistant infections. These findings underscore the need to consider CAZ-AVI in treatment guidelines and emphasize the importance of antibiotic stewardship programs to optimize its use and prevent resistance. Ongoing monitoring of resistance patterns and patient outcomes is essential to ensure its long-term efficacy.
