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

backgroundAneurysmal bone cysts (ABCs) are locally destructive, blood-filled benign bone lesions traditionally regarded as reactive rather than true neoplastic lesions. ABCs typically affect the proximal humerus, distal femur, proximal tibia, and spine. Involvement of the calcaneus is rare, representing approximately 1.6% of reported cases. A PubMed search identified nine publications describing 22 cases of calcaneal ABCs. Here, we report a rare case of ABC arising in the calcaneus and review the relevant literature. CASE PRESENTATION: A 17-year-old Japanese male with no relevant medical history presented with left calcaneal pain and gait disturbance. The patient underwent curettage with phenol-ethanol ablation and artificial bone packing (β-tricalcium phosphate [β-TCP], AFFINOS®, KURARAY Co., Tokyo, Japan). No local tumor recurrence was observed at the 36-month follow-up.

conclusionsThis case highlights a rare ABC arising in the left calcaneus of a 17-year-old Japanese male, with no recurrence after 36 months. Although adjuvant therapy was performed in this case, additional cases are required to clarify its necessity in the management of calcaneal ABC.
