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

purposeTo clarify particularly how febrile neutropenia-related hospitalization (FNH) affects patients' daily lives, by analyzing real-world data on FNH among patients with early breast cancer (EBC) receiving perioperative chemotherapy in Japan.

methodsThis retrospective nationwide large-scale database study was conducted using anonymized claims data from 2010 to 2020. The patients with EBC who had available surgical records were included. Men, those aged < 18 years, and those who had not available chemotherapy records were excluded. FNH was defined as hospitalization during perioperative chemotherapy for EBC, with administration of intravenous antibacterial drugs and a diagnosis of FN, sepsis, infection, or fever.

resultsThe analysis population included 33,310 EBC patients with a mean age of 56.9 years, who received a total of 267,535 perioperative chemotherapy cycles. FNH occurred in 1,910 patients (5.73%) and 2144 chemotherapy cycles (0.80%). Median duration of FNH was 6.0 days. Fourth-generation cephalosporins were the most used intravenous antibacterial drugs (50.42%). Median duration of intravenous antibacterial drugs administration was 4.0 days. Therapeutic granulocyte-colony stimulating factor (G-CSF) was used in 1285 patients (67.28%). Median cost for FNH was estimated to be 189 thousand yen in 1,474 chemotherapy cycles with FNH, in which patients received intravenous antibacterial drugs administration for 3-8 days.

conclusionThis nationwide real-world data analysis revealed the incidence, duration, treatment patterns, and medical cost of FNH in patients with EBC receiving perioperative chemotherapy in Japan. These findings indicate that FNH imposes a considerable burden on patients' daily lives, including time and financial impacts, contributing to the implementation of appropriate shared decision-making for primary G-CSF prophylaxis.
