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

Second (2nd)-generation tyrosine kinase inhibitors (TKI) (dasatinib, nilotinib) are effective in patients with all phases of chronic myeloid leukaemia (CML). Dose reductions and treatment interruptions are frequently required due to toxicity, but their significance is unknown. We analysed the impact of dose reductions/interruptions and dose intensity of 2nd-generation TKI on response and survival. A total of 280 patients with CML (all phases) were analysed. Dose reductions were considered when the daily dose was below the standard dose. Dose intensity was determined based on the percentage of the ideal dose intensity. Overall, 176 patients (63%) required treatment interruptions and/or dose reduction at least once during therapy. Dose reductions/interruptions, analysed as a time-dependent covariate, were associated with worse failure-free survival only in patients with untreated CML. Dose intensity analysis did not reveal a worse response or survival in patients who received a lower dose intensity (<100%) during therapy or during the first 6 months. In conclusion, dose reductions and treatment interruptions of 2nd generation TKI in patients with CML have a minimal impact in the response rate and survival of these patients. Further studies are required to determine whether there might be a minimum adequate dose of these agents.
