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

Watchful waiting (WW) in low tumour burden follicular lymphoma (LTB FL) defers treatment. There is a need to develop a model to predict time to treatment (TTT). We aimed to develop and externally validate a model for TTT in LTB FL. We conducted a retrospective analysis across eight centres within the Australasian Lymphoma Alliance. Two hundred and twenty-nine patients were included between 2004 and 2022 with a median follow-up of 5.0 years (range 0.5-17.8 years) and a median age was 64 years. All patients were Group d'Etude des Lymphomes Folliculaires (GELF) negative and managed with WW. Elevated lactate dehydrogenase and >4 nodal areas were independent prognostic factors associated with shorter TTT. These factors formed a prognostic model identifying three groups: low 59% (median TTT 6.34 years), intermediate 36% (median TTT 4.08 years), high risk 5% (median TTT 1.49 years) (p < 0.001). There was a higher incidence of serious complications among risk groups (low 7.5% vs. intermediate 13.3% vs. high 25%; p = 0.096). The prognostic value of the LTB-TREAT model was confirmed in an external validation cohort. The low-risk group is predicted to have a prolonged TTT with WW and a high-risk group is predicted to experience early progression in whom treatment should be considered.
