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
Patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT) face an elevated risk of infection-related mortality, particularly during the pre-engraftment period. Although systemic antibiotic prophylaxis (SAP) is commonly employed during neutropenia, it is linked to disruptions in the intestinal microbiome, increasing the risk of graft-versus-host disease (GVHD), Clostridium difficile infection (CDI), and colonization with multi-drug resistant (MDR) bacteria. In our retrospective analysis, we evaluated the safety and efficacy of an exclusively interventional antibiotic treatment (IAT) compared to SAP in adult alloHSCT patients. In comparison to SAP, IAT resulted in a significantly reduced duration of antibiotic therapy (24 vs. 18 days, p < 0.001), although the cumulative incidence (CI) of bloodstream infections (BSI) by day + 100 post-HSCT was significantly higher in the IAT group compared to SAP (40% vs. 13%, p < 0.001). However, this did not lead to a significant increase in ICU transfers (13% vs. 6%, p = ns) or a higher CI of non-relapse mortality (NRM) at 3 years (11% vs. 10%, p = ns). With a median follow-up of 1052 days, the 3-year overall survival (OS) rates were 69% and 66% for the SAP and IAT cohorts, respectively (p = ns). The CI of acute GVHD grade II-IV (30% vs. 39%) at 100 days or chronic GVHD of any grade (50% vs. 45%) at 3 years did not differ significantly between the SAP and IAT groups. There was a tendency towards a higher CI of severe chronic GVHD in the SAP cohort (28% vs. 13%, p = 0.08). Our single center experience in conducting alloHSCT without antibiotic prophylaxis but with stringent guidelines for prompt antibiotic intervention demonstrated no disadvantages in terms of OS and NRM. IAT led to significantly reduced consumption of cefotaxime, carbapenem, and glycopeptide antibiotics. In conclusion, our findings suggest that replacing SAP with the proposed IAT procedure is both safe and feasible.
