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.

Abstract
backgroundPegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) is a treatment for preventing febrile neutropenia (FN) in patients with early breast cancer. However, the optimal injection timing of PEG-rhG-CSF after chemotherapy is obscure. The trial was designed to explore the best administration timing of PEG-rhG-CSF when breast cancer patients could benefit most.
methodsPatients with early breast cancer were randomly assigned to receive a preventive injection on the 7th or 3rd day following chemotherapy. The experimental group (n = 80) received PEG-rhG-CSF treatment on day 7 after chemotherapy, whereas the control group (n = 80) received it on day 3. The occurrence of grades 3-4 neutropenia and FN in the first cycle was the primary endpoint. The secondary endpoint was the frequency of PEG-rhG-CSF dose reduction.
resultsIn comparison to the control group, the experimental group exhibited higher white blood cell count (WBC) and absolute neutrophil count (ANC) on the 9th and 13th days following chemotherapy (P < 0.05). Additionally, the incidence of grade 3-4 neutropenia was significantly lower in the experimental group (P = 0.038). Furthermore, a greater proportion of patients in the experimental group met the criteria for reducing the PEG-rhG-CSF dose compared to the control group (69.74% vs. 35.06%, P < 0.001).
conclusionsIn comparison with PEG-rhG-CSF injection on day 3 after chemotherapy, the incidence of grade 3-4 myelosuppression is lower, and the safety is more manageable after the injection on day 7. This approach potentially allows for a wider adoption of PEG-rhG-CSF dose reduction, leading to a consequential decrease in overall medical costs for patients.
