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
introductionMinimal residual disease (MRD) is the net result of the biological properties of disseminated tumour cells and the effect of the immune system and treatment to eliminate them. The aim of this study was to analyse the effect of combined chemotherapy on the immune function as determined by the neutrophil-lymphocyte ratio (NLR) and if it was associated with changes in the subtype of minimal residual disease and outcome in stage III colon cancer. METHODS AND PATIENTS: A prospective, single centre observational study; the NLR was determined immediately prior to and one, two and three months after completing chemotherapy. Circulating tumour cells (CTCs) and bone marrow micro-metastasis (mM) using immunocytochemistry with anti-CEA were determined prior to and one month after chemotherapy. The association of changes in the NLR with MRD subtypes classified as Group I (negative for CTCs and mM), Group II (positive for mM) and Group III (positive for CTCs) as a result of chemotherapy and five-year disease free progression (DFS) analysed.
resultsOne hundred and eighty eight patients participated of whom 83 (44.9%) relapsed. In non-relapsing patients the NLR significantly increased and was higher after chemotherapy compared with relapsing patients. Significant increases in the NLR were associated with changes to a better MRD prognostic subtype and decreases with a worse MRD subtype. Neither baseline NLR nor MRD subtype predicted response to chemotherapy. DFS for MRD subgroups were 88%, 56% and 6% for Groups I to III respectively.
conclusionsImmune function as measured by the NLR is associated with MRD prognostic subtypes, improvements in the NLR are associated with improvements in MRD post chemotherapy but neither baseline NLR or MRD predicted outcome.
