Agreement of medical record abstraction and self-report of breast cancer treatment with an extended recall window.
Article in Cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundMedical record abstraction (MRA) and self-report questionnaires are two methods frequently used to ascertain cancer treatment information. Prior studies have shown excellent agreement between MRA and self-report, but it is unknown how a recall window longer than 3 years may affect this agreement.
methodsThe Women's Environmental Cancer and Radiation Epidemiology (WECARE) Study is a multicenter, population-based case-control study of controls with unilateral breast cancer individually matched to cases with contralateral breast cancer. Participants who were diagnosed with a first primary breast cancer from 1985 to 2008 before the age of 55 years completed a questionnaire that included questions on treatment. First primary breast cancer treatment information was abstracted from the medical record from radiation oncology clinic notes for radiation treatment and from systemic adjuvant treatment reports for hormone therapy and chemotherapy. Agreement between MRA and self-reported treatment was assessed with the kappa statistic and corresponding 95% confidence intervals (CIs).
resultsA total of 2808 participants with MRA and self-reported chemotherapy treatment information, 2733 participants with MRA and self-reported hormone therapy information, and 2905 participants with MRA and self-reported radiation treatment information were identified. The median recall window was 12.5 years (range, 2.8-22.2 years). MRA and self-reported treatment agreement was excellent across treatment modalities (kappa
conclusionsAgreement between self-reported and MRA primary breast cancer treatment modality information was excellent for young women diagnosed with breast cancer and was maintained even among women whose recall window was more than 20 years after diagnosis.
