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

purposeHypofractionated radiation therapy (HFRT) remains underused, despite multiple randomized trials showing the equivalence of HFRT to conventional fractionated radiation therapy (CFRT). We sought to retrospectively review the relationship between breast volume and toxicity for HFRT versus CFRT. METHODS AND MATERIALS: Data from 114 patients who received a diagnosis of early stage breast cancer and were treated with lumpectomy and whole breast radiation alone were reviewed. Breast cancer laterality, stage, grade, estrogen/progesterone receptor and human epidermal growth factor receptor 2 status, and systemic therapy use were recorded. Length of follow-up was calculated using the last day of radiation treatment and the date of the most recent follow-up.

resultsThe median follow-up was 42 months. A total of 83 patients were treated with HFRT and 31 with CFRT. Rates of grade ≥2 skin toxicity were significantly higher in patients undergoing CFRT compared with HFRT (76% vs 28%;

conclusionsUse of HFRT resulted in lower acute skin toxicity rates compared with CFRT. Large breast size (volume ≥1000 cm
