Randomized comparison of oral and intravenous fluid regimens after gallbladder surgery.
Trial report in Journal of the Royal Society of Medicine, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Numerous studies of post-operative fluid status have utilized sophisticated measurements of electrolyte distribution and fluid shift without relating results to clinical practice. The aim of this prospective randomized study was to investigate the response of patients undergoing abdominal surgery of moderate severity to conservative post-operative fluid administration. Forty-five patients undergoing open cholecystectomy were randomized to receive 2.51 of fluid (1 l normal saline and 1.51 5% dextrose), 1 l of normal saline, or free oral fluids (groups 1, 2, 3, respectively). Serum and urine osmolality and electrolytes were measured pre-operatively and at 24 and 48 h post-operatively. Patients remained in the study irrespective of the urine output. Plasma electrolytes and osmolality remained within normal limits in all three groups despite significant changes in urine electrolyte and osmolality in groups 2 and 3. This confirms that a conservative approach to fluid administration has no detrimental effect on hydration in fit patients with uncomplicated surgery.
