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
introductionAnaemia during chemotherapy is often left untreated. Erythropoiesis-stimulating agents are frequently used to treat overt anaemia. Their prophylactic use, however, remains controversial and raises concerns about cost-effectiveness. Therefore, we assessed the efficacy of a dose-reduction schedule in anaemia prophylaxis. MATERIALS AND
methodsThe study included patients with untreated solid tumours about to receive platinum-based chemotherapy and had haemoglobin (Hb) levels ≥11 g/dL. Epoetin-α was administered at a dose level of 3 × 10,000 U weekly as soon as Hb descended to < 13 g/dL. Dose reductions to 3 × 4,000 U and 3 × 2,000 U weekly were planned in 4-week intervals if Hb stabilised in the range of 11-13 g/dL. Upon ascending to ≥13 g/dL, epoetin was discontinued. Iron supplements of 100 mg intravenous doses were given weekly. Of 37 patients who enrolled, 33 could be evaluated. RESULTS AND DISCUSSION: Their median Hb level was 13.7 (10.9-16.2) g/dL at baseline and descended to 11.0 (7.4-13.8) g/dL by the end of chemotherapy. Anaemia (Hb < 10 g/dL) was prevented in 24 patients (73%). The mean dose requirement for epoetin-α was 3 × 5,866 U per week per patient, representing a dose reduction of 41%. Treatment failed in nine patients (27%), in part due to epoetin-α resistance in four (12%) and blood transfusion in three (9%) patients.
conclusionDose reduction was as effective as fixed doses in anaemia prophylaxis but reduced the amount of prescribed epoetin substantially.
