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

purposeThis study aimed to identify the incidence and risk factors of corneal disorders (CDs) and lacrimal passage obstruction (LPO) caused by S-1 chemotherapy. STUDY

designMulticenter prospective cohort study.

methodsThis study included patients who were administered S-1 for the first time and underwent ophthalmic evaluations for 1 year during the treatment. CD was defined as an increase of >2 points in the National Eye Institute classification. LPO was defined as an abnormality in lacrimal irrigation. Risk factors were identified via univariate and multivariate analyses.

resultsThis study enrolled 126 men and 49 women with a mean age of 68.1 (30-87) years. Over a mean follow-up of 169.6 ± 127.3 days, the incidence rates of CD and LPO were 24.6% and 14.0%, with 1-year cumulative incidence rates of 37.0% and 25.9%, respectively. The risk factors for CD were no previous use of eye drops (hazard ratio [HR] 3.45, p = 0.0955) and tear breakup time over 5 s prior to S-1 chemotherapy (HR 1.86, p = 0.0535). The risk factors for LPO were male sex (HR 5.00, p = 0.0311), primary tumor other than gastric cancer (HR 2.27, p = 0.0666), previous use of eye drops for dry eye (HR 21.16, p = 0.0035), and previous visual disturbance (HR 2.89, p = 0.0303).

conclusionThe high incidence of CD and LPO among patients undergoing S-1 chemotherapy warrants close monitoring of those with identified risk factors, especially within the first six months of chemotherapy.
