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

aimsTo report long-term clinical outcome of topical 1% 5-fluoruracil (5-FU) as a sole treatment of ocular surface squamous neoplasia (OSSN).

methods41 patients affected by OSSN were included. Each patient underwent full ophthalmological examination at baseline, with cytological or histological confirmation. Patients were treated by topical chemotherapy with 1% 5-FU four times a day for 4 weeks. One course was defined as 4 weeks of topical chemotherapy. Adjunctive courses were administered after 1 month of chemotherapy-free interval.

resultsMean follow-up was 105±32 months (range 60-171 months). Complete tumour regression was achieved in 34 cases (83%) after a mean of 1.5 courses (range, 1-3 courses). Univariate analysis revealed that complete response was significantly related to tumour thickness <1.5 mm (p=0.005), lack of fornix or tarsal involvement (p=0.015 and p=0.009, respectively) and the absence of multifocality (p=0.002). Histopathological diagnosis (intraepithelial neoplasia vs squamous cell carcinoma, p=0.019) and American Joint Committee on Cancer (AJCC) classification (T1 vs T2 or T3) (p=0.028) were also related to incomplete tumour response. In a multivariate analysis, just tumour thickness >1.5 mm (p=0.045) and multifocality (p=0.023) were correlated with incomplete tumour response. Transient and reversible low-to-mild local side effects were documented in 19 (48%) eyes.

conclusionTopical 5-FU, as a sole therapy, is a long-term safe and effective treatment for patients affected by preinvasive OSSN and for a limited proportion (50%) of invasive OSSN.
