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

Objective: We retrospectively analyzed breast cancer patients who received adjuvant radiotherapy to determine the incidence of lymphocytopenia and its risk factors. Methods: We reviewed 812 patients with breast cancer who received postoperative radiotherapy. Patients were divided into two groups based on the use of chemotherapy, and a generalized linear regression model was used to explore predictive factors for grade 2 or higher lymphocytopenia. We also examined the effect of lymphocytopenia on overall survival. Results: Grade 2 or higher lymphocytopenia was observed in 19.4% of patients who did not receive chemotherapy and 45.1% of patients who received chemotherapy. In multivariate analysis, bilateral disease, regional lymph node irradiation, and baseline lymphocytopenia were associated with lymphocytopenia in patients who did not receive cytotoxic chemotherapy. Regional lymph node irradiation, baseline lymphocytopenia, use of antimetabolites, and use of molecular-targeted agents were associated with lymphocytopenia in patients treated with chemotherapy. In the survival analysis, lymphocytopenia was associated with worse overall survival only in patients treated with cytotoxic chemotherapy ( Conclusion: The analysis revealed the incidence and risk factors of lymphocytopenia after postoperative radiotherapy in patients with breast cancer.
