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

To analyze the effects of metformin in reducing radiation-induced cardiac toxicity (RICT) risk during adjuvant radiotherapy (RT) after surgery for early-stage breast cancer women. We compare the consecutive occurrence of major heart events (heart failure and coronary artery disease) in women with early-stage breast cancer receiving adjuvant breast RT with metformin and in those receiving RT without metformin. A retrospective national cohort study was conducted using the Taiwan Cancer Registry of 2004-2014. This study included 6,993 women with early-stage breast cancer who received adjuvant breast RT. Metformin users were defined as patients prescribed metformin for >28 days during adjuvant breast RT. An inverse probability of treatment weighting (IPTW) Cox hazards model was used to estimate metformin effects on the occurrence of major heart events. Among women with breast cancer status post-surgery under adjuvant breast RT, 2,062 were prescribed metformin and 4,931 were not prescribed metformin. Cox proportional hazard regression analysis, with adjustment using IPTW, indicated that metformin use during adjuvant breast RT significantly reduces the risk of major heart events (adjusted hazard ratio [aHR], 0.789; 95% confidence interval [CI], 0.645-0.965;
