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

backgroundWe evaluated the prognostic significance of neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) in patients with multiple myeloma (MM).

methodsIn total, we retrospectively analyzed 315 newly diagnosed MM patients and calculated NLR and PLR from the complete blood count of the untreated patients. We further assessed the role of pretreatment NLR and PLR on overall survival (OS) and progression-free survival (PFS).

resultsMultiple myeloma patients with high NLR (≥2) experienced shorter OS (P=.02) and PFS (P=.01) compared with patients with low NLR (<2). Furthermore, among the patients with conventional chemotherapy, elderly patients, or patients with advanced stages, high NLR (≥2) was found to have a negative prognostic impact on OS and PFS. In the multivariate Cox analysis, we confirmed that the NLR was an independent prognostic factor for both OS and PFS (P=.000). But the differences in OS or PFS by PLR were not found in MM patients.

conclusionsOur study suggests that NLR not PLR can be acted as an independent prognostic factor for analyzing the clinical outcome of MM patients.
