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

objectiveTo assess mortality and morbidities in very low birthweight (VLBW) infants before and after changing to a restrictive blood transfusion guideline (RTG). STUDY

designThis is a large retrospective study comparing outcomes of a liberal transfusion guideline (LTG) and RTG in VLBW infants admitted to a large single neonatal intensive care unit. Blood and platelet transfusion details, mortality, and diagnoses of frequently diagnosed morbidities were collected for each infant.

resultsMortality was similar between RTG and LTG groups (6.8% vs. 6.3%, p = 0.755). Rates of periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), sepsis and the diagnosis of necrotizing enterocolitis (NEC) within 48 h of a PRBC transfusion were significantly lower with RTG (p < 0.05). Chronic lung disease was similar between groups.

conclusionRTG are safe compared to LTG, and are associated with lower rates of PVL, ROP, transfusion-associated cases of NEC and sepsis.
