1 · What the graph read from it

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.

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.

Abstract

purposeDiabetes (DM) and hyperglycemia during chemotherapy increase the risk of toxicity, yet the prevalence and patterns of hyperglycemia in early-stage breast cancer (ESBC) patients undergoing chemotherapy with concurrent dexamethasone remain poorly understood.

methodsWe conducted a prospective single-arm study using FreeStyle Libre Pro continuous glucose monitoring in patients with ESBC receiving chemotherapy from 12/2020-2/2022. Sensors measured interstitial glucose every 15 min and were reapplied every 2-3 weeks. Primary endpoints were (1) prevalence of hyperglycemia (≥ 1 reading ≥ 140 mg/dL), and (2) for those with hyperglycemia, the proportion of time spent hyperglycemic. Secondary endpoints included baseline glucose tolerance by A1c, changes in glucose-related biomarkers, and changes in patient-reported neuropathy, quality of life, and fatigue. Analysis was stratified by baseline A1c (euglycemic < 5.7%, prediabetes [pre-DM] 5.7-6.4%, diabetes [DM] ≥ 6.5%).

resultsAmong 20 evaluable patients (median age: 60, BMI: 29.5 kg/m

conclusionAll patients receiving chemotherapy for ESBC experienced hyperglycemia, with time spent hyperglycemic varying significantly by baseline A1c. Future research should explore approaches to and benefits of improving glycemic control during treatment in patients with baseline dysglycemia.
