Baseline and On-Treatment Absolute Lymphocyte Count-Defined Lymphopenia in Solid Tumors Treated With Immune Checkpoint Inhibitors: A Systematic Review With Structured Qualitative Synthesis.
Review in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Immune checkpoint inhibitors are widely used in solid tumors, but patient outcomes remain variable, and practical prognostic markers are still being clarified. This systematic review examined whether lymphopenia, defined by absolute lymphocyte count, assessed before treatment and/or during therapy, is associated with survival outcomes in adults with solid tumors treated with immune checkpoint inhibitors. A total of 21 studies were included, with sample sizes ranging from 22 to 18,186 patients. Several studies reported associations between lower absolute lymphocyte count and less favorable survival outcomes, although findings were heterogeneous and context-dependent. Overall, the available evidence suggests that absolute lymphocyte count-defined lymphopenia may have prognostic relevance in some settings, although substantial heterogeneity across studies limits firm conclusions and highlights the need for more standardized research.
