Increased Incidence and Risk Factors of Infections by Extended-Spectrum β-Lactamase-Producing Enterobacterales During the COVID-19 Pandemic: A Retrospective Case-Control Study.

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
Purpose: To investigate changes in the incidence of infections by extended-spectrum β-lactamase-producing Patients and Methods: The study was a single-center retrospective case-control design. A total of 107 patients infected by ESBL-E during the COVID-19 pandemic were selected as the case group, while 214 uninfected patients selected by 1:2 propensity score matching (PSM) acted as the control group. Univariate analysis, LASSO logistic regression, and multivariate logistic regression were used to determine the risk factors for ESBL-E infection. An interrupted time series was used to analyze the changes in the incidence of ESBL-E infections in hospitalized patients during the COVID-19 pandemic. Results: The incidence of infection with ESBL-E showed a significant increase during COVID-19 (3.42 vs 4.92 per 1000 patients, p = 0.003). The incidence of ESBL-E infections increased at an average rate of 0.45 per 1000 patients per week compared to the pre-pandemic period (p = 0.022). Multivariate logistic regression analysis showed that a length of hospitalization ≥ 15 days (OR: 2.98 (1.07-8.28), chronic kidney disease (OR: 4.25 (1.32-13.70), white blood cell (WBC) > 9.5×10^9/L (OR: 3.04 (1.54-6.01), use of hormonal drugs (OR: 2.38 (1.04-5.43), antibacterial drug use 1 type (OR: 5.38 (2.04-14.21), antibacterial drug use 2 types (OR: 23.05 (6.71-79.25) and antibacterial drug use ≥ 3 types (OR: 88.35 (8.55-912.63) were independent risk factors for infection with ESBL-E, while chronic obstructive pulmonary disease (COPD) was a protective factor (OR: 0.14 (0.03-0.66). COVID-19 was not an independent risk factor for infection by ESBL-E. Conclusion: During the COVID-19 pandemic, the incidence of infections by ESBL-E increased significantly. Increased exposure to traditional risk factors were the main reasons, however, COVID-19 was not an independent risk factor for ESBL-E infection.
