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

Patients with cancer-induced bone disease, including primary bone cancers such as osteosarcoma (OS) and metastases from other tissues of origin, present a high unmet medical need. We present a potential therapeutic approach built upon a proven bone-targeting bisphosphonate conjugate platform with the known synergies of gemcitabine (GEM) and docetaxel (DTX). The synthesis of rationally designed GEM-IB, the conjugate of GEM-5'-phosphate with ibandronate (IB), is presented. GEM-IB as a single agent or in combination with DTX demonstrated reduced tumor burden, preservation of the bone architecture, and improved the survival in a murine model of OS. This is the first demonstration of a bone-targeting conjugate in combination with a second drug to create effective drug ratios in the bone compartment.
