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

The International Prognostic Index (IPI) and other prognostic models cannot accurately classify risks in patients with lower-risk diffuse large B cell lymphoma (DLBCL). This study retrospectively analyzed serum levels of ferritin (500 and ≥ 500 ng/mL) and other reported risk factors for survival in 312 patients. High and high-intermediate risk IPI scores (hazard ratio (HR) [95% confidence interval (CI)] 2.22 [1.33, 3.72], P = 0.002 and 2.29 [1.33, 3.93], P = 0.003, respectively) and ferritin concentration ≥ 500 ng/mL (HR [95% CI] 2.22 [1.37, 3.60], P = 0.001 and 2.18 [1.31, 3.63], P = 0.003, respectively) were independent poor prognostic factors for 5-year progression-free survival (PFS) and overall survival (OS) rates in all patients. Additionally, high ferritin level (≥ 500 ng/mL) was an independent poor prognostic factor for PFS and OS in patients with lower-risk IPI (HR [95% CI] 3.37 [1.36, 8.33], P = 0.009 and 3.29 [1.23, 8.83], P = 0.0018, respectively). In conclusion, serum ferritin levels may be helpful in predicting survival in patients with DLBCL, especially in those with lower-risk IPI scores.
