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

backgroundThe International Study Group of Pancreatic Fistula (ISGPF) defines postoperative pancreatic fistula (POPF) based on drain fluid amylase (DFA) levels. However, drain malposition can compromise the reliability of DFA in detecting POPF. This may trigger premature drain removal, delayed recognition of clinically relevant POPF (CR-POPF), and escalation of morbidity. We evaluated how drain position modifies the diagnostic performance of DFA after PD.

methodA retrospective analysis of 334 patients who underwent PD (June 2019-December 2023). Drain position was assessed using postoperative imaging and DFA levels were measured on postoperative day3. The primary aim was the incidence of drain malposition, while secondary aims included its impact on the diagnosis of CR-POPF, SFC.

resultAmong 334 patients, the drain was well-positioned in 255 patients (76.4%) and malpositioned in 79 patients (23.6%). High DFA levels were strongly associated with proper drain positioning (152/164, 92.7%). However, low/normal DFA levels often reflected drain malposition, with 67/170 patients(39.4%) incorrectly classified, leading to potential false-negative results. Malpositioned drains patients had a significantly higher SFC(p < 0.001) and longer hospital stay (p < 0.001). Multivariable analysis confirmed drain malposition as an independent predictor of CR-POPF (OR 4.74, 95% CI: 1.86-12.06, p = 0.001), small pancreatic duct(OR 10.59, 95% CI: 3.92-28.62,p < 0.001) and low preoperative albumin (OR 0.07, 95% CI: 0.02-0.24, p < 0.001).

conclusionDrain malposition significantly impacts DFA reliability with false-negative diagnosis. Revising the ISGPS definition to incorporate drain positioning alongside DFA levels may improve diagnostic accuracy in defining POPF.
