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

objectivesOsteosarcoma is the most common malignant bone tumor in childhood. Although a poorer prognosis has been described in older patients, few reports have focused solely on primary osteosarcoma. We evaluated the clinical features of elderly patients with primary osteosarcoma. MATERIALS AND

methodsNinety-four patients were included in this retrospective study, and we divided them into 2 groups (older patients and younger patients) based on a cut-off age of 40 years. The patients' information, including age, tumor type, location, presence of metastasis, American Joint Committee on Cancer (AJCC) stage, treatment-related factors, local and distant relapse, and outcome, was collected. We compared the clinical courses between the 2 groups in all and only deceased patients.

resultsIn all patients, the frequency of chemotherapy in the older group was significantly lower than in the younger group (p < 0.001), and tumors were more frequent in axial bone in the older patients (p = 0.041). Only in patients with surgical treatment, histological effectiveness after chemotherapy in the older group was lower than in the younger group (p = 0.041). The older patients showed a poorer prognosis (p = 0.031). However, the 5-year overall survival rate in the older patients was more favorable than that in the younger patients only among deceased patients (p =0.032). Only the existence of metastasis affected the prognosis in older patients (p = 0.012).

conclusionPrimary osteosarcoma in elderly patients showed a high incidence of axial bone involvement, a low rate of chemotherapy, and resistance to chemotherapy. Although the final life prognosis is poor, survival may be relatively prolonged.
