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.
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
backgroundStudies on sarcoidosis-lymphoma syndrome are scarce, and the association between these diseases is poorly understood. Aim: To analyse the features of three types of sarcoidosis-lymphoma association (SLA) according to the time of diagnosis of both diseases and to compare the features of patients who presented with sarcoidosis before lymphoma with those of patients with sarcoidosis alone (SA) in order to identify predictive factors of lymphoma development. Design: A multicentre retrospective comparative study was conducted in two hospitals in Lyon and one hospital in Saint-Etienne, France, between 1999 and 2022. Methods: In the SLA group, 46 patients were included and compared to 92 patients of the SA group. Demographic characteristics, medical history, clinical presentation, laboratory and imaging findings, treatments, and outcomes were collected and analysed from medical records. Results: The age at lymphoma diagnosis was significantly higher in the group in which sarcoidosis preceded lymphoma [65.9 years when sarcoidosis preceded lymphoma vs 48.3 years when both diseases occurred simultaneously vs 44.5 years when sarcoidosis followed lymphoma, p<0.001]. Hodgkin's lymphoma was significantly more frequent in patients from group "simultaneous diseases" (p<0.001). There were significantly more autoimmune diseases (15.2% vs 2.17% p=0.007) in the SLA group, and patients with SA presented more frequently with night sweats (45.7% vs 11.6% p<0.001). Conclusions: No robust predictive factor of lymphoma development in patients with sarcoidosis was identified. However, it highlighted distinct clinical scenarios according to when lymphoma is diagnosed that must be taken into account by clinicians for disease management.
