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
backgroundIn Japan, the administration of extra-hypotonic fluids (approximately 35 mmol/L of sodium) as maintenance fluid is still the mainstream practice, and there have been relatively few reports on maintenance intravenous fluid therapy. Since 2014, our institution has administered maintenance fluids containing 83 mmol/L of Na (HALF) after diuresis is achieved post-Kasai portoenterostomy for biliary atresia (BA). We investigated whether hyponatremia is induced by the administration of half saline during postoperative maintenance of infants with BA.
methodsPatients who underwent surgery for BA at our institution were included. The serum sodium concentration ([Na]) before and after surgery and the incidence of hyponatremia were compared between patients administered fluids with [Na] of 35 mmol/L (exHYPO group, 59 patients) and those with [Na] of 83 mmol/L (HALF group, 20 patients).
resultsThe median age of patients was 59 days. There were no significant differences in the background or preoperative [Na] between groups. There was a significant decrease in [Na] on postoperative day 3 (POD3) in the exHYPO group compared with the preoperative [Na] value in the exHYPO group and the [Na] value on POD3 in the HALF group. There were no significant differences in [Na] before and after surgery in the HALF group. The odds ratio was 21.0, and the 95% confidence interval was 3.31-130, indicating that the exHYPO group had an increased risk of hyponatremia.
conclusionAdministration of half saline as maintenance fluid can maintain [Na] levels during postoperative care of infants with BA.
