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

backgroundDiscontinuation of postoperative S-1 adjuvant monotherapy is a frequent problem in the management of patients with gastric cancer.

methodsA total of 355 stage II/III gastric cancer patients who underwent gastrectomy and adjuvant S-1 were retrospectively analyzed using a multicenter dataset. We randomly assigned patients into either discovery or validation cohort in a 2:1 ratio. In the discovery cohort, 29 parameters were assessed as candidate factors to predict discontinuation of S-1 adjuvant within 6 months. A scoring system was designed using independent risk factors identified by the multivariate analysis. Reproducibility was tested in the validation cohort.

resultsOverall, 92 patients (25.9%) discontinued the treatment within 6 months because of adverse effects. Age, preoperative urea nitrogen (UN) and the preoperative albumin-to-bilirubin index (ALBI) showed the highest area under the curve (AUC) for the discontinuation of S-1 adjuvant within 6 months in each category: body status, blood tests and indices. In the multivariate analysis, age ≥ 64 years, preoperative UN ≥ 15.2 mg/dl and preoperative ALBI ≥ -0.265 were identified as independent risk factors. A scoring scale consisting of these three factors was developed for the prediction of drug discontinuation and demonstrated a greater AUC (0.728) than that of each of the three constituents. The time to treatment discontinuation decreased incrementally as the risk score increased. The reproducible findings were confirmed in the validation cohort.

conclusionsWe identified risk factors and developed a scoring scale to predict S-1 adjuvant monotherapy discontinuation in patients with stage II/III gastric cancer.
