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
purposeSulbactam (SBT) is one of the most significant treatments for patients with extensively drug-resistant Acinetobacter baumannii (XDR-AB). However, the efficacy and safety of SBT and its high dose regimen has not been well documented. This retrospective study aimed to assess the efficacy and safety of SBT-based treatment, particularly at high-dose (≥ 6 g/day), for XDR-AB infection.
methodA total of 52 XDR-AB infected patients treated with intravenous SBT at Peking Union Medical College Hospital were included. The primary outcome was 28-day all-cause mortality, while the secondary outcome was 14-day clinical response and the time of response. The formulation of SBT in our study is 0.5 g per vial.
resultsAmong the patients, the 28-day all-cause mortality rate was 36.5% (19/52), and the favorable 14-day clinical response rate was 59.6% (31/52). The 28-day mortality was independently associated coinfection with gram-positive bacteria (GPB) and a shorter duration of therapy. Patients with intracranial infection might have a longer survival time. A favorable 14-day clinical response was associated with the dose of SBT, and a longer treatment duration. However, the higher creatinine clearance (CrCl) associated with a worse clincal response. In addition, a higher SBT dosage was significantly correlated with a shorter time to clinical response. No adverse effects related were reported.
conclusionThe single-agent formulation of SBT emerges as a promising alternative for the treatment of XDR-AB infection, such as intracranial infection, particularly at high doses (≥ 6 g/day). Besides, longer duration of treatment correlates with higher survival rate and better favorable clinical response. Higher CrCl negatively correlates with favorable clinical response.
