The influence of preoperative neoadjuvant chemotherapy on the incidence of post-induction hypotension in patients with ovarian cancer- a retrospective observational cohort study.
Observational study in BMC anesthesiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeNeoadjuvant chemotherapy has become one of the initial treatment modalities for advanced ovarian cancer. Previous studies have indicated that preoperative neoadjuvant chemotherapy may reduce patients’ requirements for anesthetic agents. This study aims to investigate the effect of neoadjuvant chemotherapy on post-induction hypotension. PATIENTS AND
methodsThis study enrolled a total of 532 patients, with 482 included in the primary analysis. Multivariable logistic regression and propensity score matching were used to analyze the association between Neoadjuvant chemotherapy and post-induction hypotension. Multiple sensitivity analyses were performed, including the use of alternative MAP thresholds, multiple imputation, inverse probability weighting, and E-value methods.
resultsThis study enrolled a total of 532 patients, of whom 482 were included in the primary analysis. After propensity score matching, each group included 161 patients. The incidence of PIH were 29.19% in the non-NC group and 52.80% in the NC group (p < 0.001). Neoadjuvant chemotherapy was identified as an independent risk factor for post-induction hypotension in patients with ovarian cancer [adjusted OR 2.89 (1.90–4.42)], p < 0.001. Sensitivity analyses further supported the main conclusion.
conclusionPatients receiving neoadjuvant chemotherapy were 2.89 times more likely to experience post-induction hypotension compared with those who did not, within the first 20 min after anesthesia induction.
