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

Purpose: Intravascular brachytherapy (IVBT) has a well-proven activity against coronary restenosis of a native vessel or a single bare metal stent. However, its effectiveness for multiple recurrent same-vessel in-stent restenoses (ISRs) is unproven. The objective of this study was to determine if IVBT prolongs the ISR-free interval in recalcitrant lesions. Methods and Materials: ISR-free intervals before and after IVBT for individual patients were compared. T1 was the ISR-free interval prior to IVBT, and T2 was the ISR-free interval after IVBT. Accrual was sought from patients with a prior ISR-free interval of less than 2 years. Standard radiation techniques were used, with doses of 18, 23, or 34 Gy prescribed at 2 mm from the radiation source. ISR-free intervals before (T1) and after IVBT (T2) were compared. Results: Twenty-six vessels in 19 patients were studied. ISR-free intervals prior to IVBT ranged from 25 to 317 days (median, 96 days) compared with ISR-free intervals after IVBT that ranged from 30 to 612 days (median, 350 days; Conclusion: The results support the use of IVBT to prolong the ISR-free interval in recalcitrant ISRs.
