Association Between Antibiotic and Outcomes of Chemoimmunotherapy for Extensive-Stage Small Cell Lung Cancer: A Multicenter Retrospective Study of 132 Patients.

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
introductionTo evaluate the impact of antibiotic (ATB) exposure on the outcome of chemoimmunotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC).
methodsIn this multicenter retrospective study, 132 patients with ES-SCLC who received chemoimmunotherapy were included from three hospitals in China. Patients receiving ATB within 30 days prior to initiating ICI therapy (p-ATB) and those receiving concurrent ICI therapy until cessation (c-ATB)were compared to those who did not (n-ATB). Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and immune-related adverse events (irAEs) were assessed. To avoid immortal time bias, c-ATB was analyzed as a time-dependent covariate in the Cox proportional hazards model.
resultsAmong the 132 patients, 25 were included in the p-ATB group and 26 in the c-ATB group, while 81 patients were categorized in the n-ATB group. Multivariate analysis revealed no significant differences in PFS (aHR = 1.028, 95% CI: 0.666-1.589, p = 0.900) and OS (aHR = 0.957, 95% CI: 0.549-1.668, p = 0.877) between the p-ATB and n-ATB groups. Similarly, p-ATB had no significant impact on ORR (p = 0.510) or irAEs (p = 0.516). The use of c-ATB had no significant effect on either PFS (aHR: 1.165, 95% CI: 0.907-1.497; p = 0.232) or OS (aHR: 1.221, 95% CI: 0.918-1.624; p = 0.171) by multivariate analysis.
conclusionsp-ATB has no significant impact on PFS, OS, ORR, or the incidence of irAEs in ES-SCLC patients receiving chemoimmunotherapy. Similarly, c-ATB does not seem to affect PFS or OS.
