1 · What the graph read from it

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.

2 · The registry

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

backgroundCurrently, there are no reports on the subsequent treatment of patients with ovarian cancer who exhibited platinum-resistant recurrence during treatment with poly (ADP-ribose) polymerase (PARP) inhibitors. This retrospective study was aimed at evaluating the efficacy and safety of single-agent chemotherapy combined with bevacizumab (BEV) in such patients. PATIENTS AND

methodsThe efficacy and safety of the treatment were evaluated in 16 patients with ovarian cancer, fallopian tube cancer, or primary peritoneal cancer diagnosed with platinum-resistant recurrence during PARP inhibitor treatment between April 2019 and June 2025. Chemotherapy was administered with paclitaxel alone or nogitecan alone in combination with BEV and generally continued until the disease progressed.

resultsThe median number of single-agent chemotherapy cycles with BEV was 6 (range: 1-20). The objective response and disease control rates were 31.3% and 75.0%, respectively. The median progression-free survival 2 and post-progression survival were 5.5 months [95% confidence interval (CI) = 4.0-6.0] and 17 months (95%CI = 10.0-29.0), respectively. Grade 3 or higher hematological toxicities were observed, including leukopenia, neutropenia, anemia, and thrombocytopenia in 7, 9, 1, and 3 patients, respectively. Non-hematological toxicities included hypertension in three patients and nausea, vomiting, fatigue, proteinuria, thrombosis, ileus, and heart failure in one patient each. None of the patients discontinued chemotherapy because of adverse events or treatment-related deaths.

conclusionBEV-combined single-agent chemotherapy has potential efficacy even in the challenging setting of platinum-resistant recurrence during PARP inhibitor treatment of ovarian cancer.
