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.

2 · The registry

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

backgroundChildren with acute lymphoblastic leukemia (ALL) may develop hypoglycemia, potentially attributable to mercaptopurine (6-MP) during long-term maintenance chemotherapy. Since hypoglycemia is harmful to childhood neurodevelopment, it is necessary to examine its occurrence during chemotherapy with and without 6-MP beyond the maintenance stage for ALL, along with the risk factors.

methodsALL patients received CAM-1 regimen (cyclophosphamide, cytarabine, and 6-MP). 6-MP was randomized to conventional administration at night before bedtime (Group A) or in the afternoon between lunch and dinner (Group B). Children with acute myeloid leukemia received non-6MP-containing chemotherapy (Group C).

resultsGroup C showed no hypoglycemia. Among patients on CAM-1, 33% developed hypoglycemia, 48% of whom were symptomatic. There was no significant difference in hypoglycemic incidence (P = 0.933) between Groups A and B. No further hypoglycemic episodes were observed after shortening overnight fasting period in most cases. Multivariate analysis identified young age, higher serum bilirubin levels, and longer overnight fasting as significant risk factors for hypoglycemia in children receiving 6-MP.

conclusionHypoglycemia is also prevalent in children exposed to short-term 6-MP but not in those without such exposure. Shortening overnight fasting period, rather than changing 6-MP schedule, is more critical in preventing hypoglycemia in young children. IMPACT: This study reveals that hypoglycemia occurs frequently in children with ‌short-term exposure to 6-MP‌, as documented for long-term exposure‌ in published literature. The data demonstrate that it is 6-MP that is directly associated with hypoglycemia. Prolonged durations of overnight fasting, especially in younger individuals with hepatotoxicity, constitute a risk factor for developing hypoglycemia. Shortening the overnight fasting period, rather than changing the 6-MP schedule, is critical to prevent hypoglycemia and adverse neurodevelopment in children, even if they are receiving short-term 6-MP treatment.
