The utility of electronic frailty index in cancer patients undergoing chemotherapy.
Article in British journal of cancer, 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
backgroundFrail patients with cancer (Ca) have worse survival. Current methods of assessment of fitness (performance status) for cancer treatment, such as chemotherapy, are time -consuming and often not used by practicing oncologists. The electronic frailty index (SCARF) is derived from a cumulative deficit frailty model and provides a measure of frailty alongside pre-existing conditions. We used this methodology to investigate whether it can predict outcomes of chemotherapy in patients with Ca.
methodsThe study conducted data analysis of Ca patients treated with chemotherapy in England, years 2015-2018; stage II-III breast Ca, stage III colon Ca and stage IIIB-IV non-small-cell lung Ca. The data was linked with hospital admissions to calculate 30-day chemotherapy mortality, overall survival and SCARF.
resultsThe SCARF was calculated for 78,799 patients. The risk of dying within 30 days of chemotherapy in severely frail patients with colorectal cancer ≥70 y.o. was twice that of the <70 y.o. (OR 2.04 -95% CI 1.58-2.64, mild frailty 1.07-95% CI 0.78-1.45); and 6 times higher in breast cancer (OR 5.73-95% CI 2.66-12.32, mild frailty OR 1.45 95% CI 0.78-2.71).
conclusionThe SCARF index predicts poor outcomes from SACT, particularly in breast and colon cancer, and it requires further evaluation.
