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

purposeBreast cancer patients receiving adjuvant radiotherapy (RT) benefit from local control. However, RT can give rise to increased fatigue, lowering quality of life. The aim of this study was to prospectively identify trends and risk factors in patient-reported fatigue associated with breast RT. MATERIAL AND

methodsPatients were assessed using the Edmonton Symptom Assessment Scale (ESAS) before, once per week during RT, up to 6 weeks after RT completion, and 1-3 months post RT. Patients were included in the analysis if the ESAS was completed before, at least once during, and at least once after RT.

resultsA total of 651 patients were included. Fatigue scores increased significantly during weeks 1-3 (p < 0.001) and weeks 5-6 (p < 0.0001) during RT compared to baseline. After RT completion, fatigue scores did not change significantly compared to baseline. Mastectomy patients who received previous chemotherapy experienced significantly more fatigue compared to mastectomy patients without previous chemotherapy (p = 0.0002). Patients less than 50 (p = 0.002), 50-59 (p = 0.007), or 60-69 (p = 0.048) years of age at RT start were more likely to have higher proportions of moderate or severe fatigue compared to patients ≥ 70 years of age.

conclusionsFatigue associated with breast irradiation increased up to 6 weeks during RT and returned to near baseline scores at 1-3 months post treatment. Given that fatigue was significant in mastectomy patients, further research is needed to reduce fatigue among this cohort, especially those who have received previous chemotherapy and younger patients who are receiving breast RT.
