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

backgroundSLE is a chronic autoimmune disease with heterogeneous manifestations. This study evaluated the discriminative value of complete blood count-derived biomarkers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), eosinophil-to-lymphocyte ratio (ELR), basophil-to-lymphocyte ratio (BLR), mean platelet volume and red cell distribution width (RDW), in identifying lupus flares.

methodsThis cross-sectional study was conducted over 10 years in the internal medicine department of Sahloul Hospital. SLE patients were classified by disease activity using Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K): flare (SLEDAI-2K >6) or remission (SLEDAI-2K ≤6). A matched group of healthy controls was included. Comparisons were made between flare/remission and flare/controls. Discriminative performance of biomarkers was evaluated using receiver operating characteristic analysis, with sensitivity (Se), specificity (Sp) and area under the curve (AUC) determined for the optimal cut-off values.

resultsThe study included 83 SLE patients (40 flares, 43 remission) and 85 controls, median age of 32 years and a sex ratio of 0.16. Compared with remission, flares had significantly higher NLR and RDW and lower ELR. The most discriminative biomarkers were RDW (AUC=0.708, cutoff ≥14.65, Se =75.9%, Sp =60.6%), NLR (AUC =0.636, cutoff ≥2.63, Se =72.4%, Sp =51.5%) and ELR (AUC =0.647, cutoff ≤0.0076, Se =74.4%, Sp =65%). Compared with controls, flares showed higher NLR, PLR, MLR, RDW and lower ELR and BLR. Best performances were RDW (AUC =0.864, cutoff ≥13.85, Se =89.7%, Sp =75.3%), NLR (AUC =0.822, cutoff ≥2.28, Se =79.3%, Sp =76.5%) and ELR (AUC =0.775, cutoff ≤0.029, Se =87.1%, Sp =70.3%). SLEDAI-2K correlated positively with NLR (r =0.228), PLR (r =0.238), RDW (r =0.303) and negatively with ELR (r =-0.317).

conclusionsThese biomarkers may serve as simple, accessible and cost-effective tools for detecting lupus flares, particularly in resource-limited settings.
