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

BACKGROUND AND

objectiveUnderstanding the patient experience is important for identifying the unmet need in chronic lymphocytic leukemia. The current study aimed to develop a comprehensive chronic lymphocytic leukemia conceptual model.

methodsThe conceptual model was based on literature searches, review of chronic lymphocytic leukemia patient blogs/forums, and interviews with five expert clinicians, with 20 patients who received at most one treatment (first line) for their chronic lymphocytic leukemia, and with 20 patients with relapsed or refractory chronic lymphocytic leukemia. De-identified interviews were transcribed, coded, and evaluated using qualitative data analysis software.

resultsThirty-five prevalent chronic lymphocytic leukemia-related symptom and impact concepts were identified from literature searches, patient blogs/forums, and clinician interviews. Patient interviews confirmed the identified concepts and revealed five additional concepts. Fatigue-related sub-components were identified from how patients described their fatigue, covering symptoms (tiredness/need for sleep, lack of energy, weakness, cognitive fatigue), and impacts (decreased ability to maintain their social, familial, or professional role, decreased physical functioning, frustration). Three versions of the conceptual model were created: an overall model with all concepts; a model highlighting the most prominent concepts in first line; and a model highlighting the most prominent concepts in relapsed or refractory disease. Prominent concepts in both first line and relapsed or refractory disease were fatigue-related symptoms and impacts, muscle/joint aches, night sweats, bruising, fever, recurrent infections/illness, insomnia, decreased cognitive/emotional functioning, anxiety/worry, stress, depression, financial difficulty, and fear of death. Dyspnea and cough were prominent in first line only, and enlarged lymph nodes, headaches, pain/discomfort, weight loss, nausea/vomiting, and infusion reactions were prominent in relapsed or refractory disease only.

conclusionsThe results show that fatigue is a dominant issue affecting patients with chronic lymphocytic leukemia. The three versions of the conceptual model can help researchers to understand patients' unmet needs and guide the patient-reported outcome strategy for clinical trials.
