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

purposeNeonatal liver tumors, although rare, can cause life-threatening conditions immediately after birth, requiring urgent surgical intervention. We retrospectively reviewed neonatal liver tumors requiring early postnatal hepatectomy to identify the factors necessitating early surgical intervention.

methodsWe retrospectively analyzed neonatal liver tumors that required surgical resection in the early postnatal period at our institution between 1980 and 2021. Clinical records were reviewed for gestational age, birth weight, tumor characteristics, surgical procedures, and perioperative complications.

resultsSeven patients were identified; four were diagnosed prenatally and three postnatally. The delivery modes included vaginal (n = 4) and cesarean (n = 3) births. The median gestational age, birth weight, tumor size, and age at surgery were 38 (range, 37-40) weeks, 3152 (2564-3898) g, 10 (2.5-12) cm, and 6 (0-62) days, respectively. The final diagnoses included hepatoblastoma (n = 3), hemangioma (n = 2), mesenchymal hamartoma (n = 1), and focal nodular hyperplasia (n = 1). Six patients presented with life-threatening systemic compromise due to tumor-related mass effect, rupture, hemorrhage, or metabolic derangement. Surgery-related complications occurred in three patients, including tumor lysis syndrome.

conclusionsNeonatal liver tumors can precipitate rapidly progressive and life-threatening systemic conditions. Although early postnatal hepatectomy carries substantial risks, timely surgical decision-making with anticipation of tumor-related complications can be life-saving and thus enable favorable long-term outcomes.
