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

purposeThe purpose of this study is to explore whether bone pain "clusters" with other symptoms in patients with bone metastases. MATERIALS AND

methodsPatients with bone metastases referred to a palliative radiotherapy clinic were asked to rate their symptom distress using the Edmonton Symptom Assessment Scale (ESAS). Analgesic consumption during the previous 24 h was captured at initial consultation. To determine interrelationships between symptoms, a principal component analysis (PCA) with "varimax rotation" was performed on the nine ESAS symptoms. This study defined a "symptom cluster" as two or more symptoms that occur together, are stable, and are relatively independent of other clusters. Patients were followed 1, 2, 4, 8, and 12 weeks post-radiation treatment by telephone. Statistical analysis was performed at each time point for both responders and nonresponders to radiation (response was defined in accordance to the International Bone Metastases Consensus Working Party).

resultsFive hundred eighteen patients with bone metastases provided complete baseline data using the ESAS. The four most prevalent symptoms were poor sense of well-being (93.5%), fatigue (92.3%), pain (84.1%), and drowsiness (81.8%). Three clusters were identified and accounted for 66% of the total variance at baseline. Cronbach's alpha coefficient demonstrated high internal reliability in the clusters, with a coefficient ranging from 0.61 to 0.81. It was observed that the clusters changed post-radiation in both responders and nonresponders and that pain clustered with different symptoms (or remained a separate symptom in responders). In nonresponders, three symptom clusters were consistently present, except in week 8.

conclusionRadiotherapy influenced the structure of symptom clusters in both responders and nonresponders. There was evidence that pain clustered out in responders of radiation to pain. It was found that pain clustered with fatigue, drowsiness, and poor sense of well-being at baseline. However, these findings must be heeded with caution, as more work is needed to clearly define symptom clusters and to understand the effects of radiation in the symptom experience of patients with bone metastases.
