Influence of preemptive analgesia on pulmonary function and complications for laparoscopic cholecystectomy.
Trial report in Digestive diseases and sciences, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Pain and diaphragmatic dysfunction are the major reasons for postoperative pulmonary complications after upper abdominal surgery. Preoperative administration of analgesics helps to reduce and prevent pain. The objective of this study was first to research the rate of pulmonary complications for laparoscopic cholecystectomy (LC) and then analyze the influence of preemptive analgesia on pulmonary functions and complications. Seventy patients scheduled for elective LC were included in our double-blind, randomized, placebo-controlled, prospective study. Randomly, 35 patients received 1 g etofenamate (group 1) and 35 patients 0.9% saline (group 2) intramuscularly 1 h before surgery. All patients underwent physical examination, chest radiography, lung function tests, and pulse oxygen saturation measurements 2 h before surgery and postoperatively on day 2. Atelectasis was graded as micro, focal, segmental, or lobar. With preemptive analgesia, the need for postoperative analgesia decreased significantly in group 1. In both groups mean spirometric values were reduced significantly after the operation, but the difference and proportional change according to preoperative recordings were found to be similar [29.5 vs. 31.3% reduction in forced vital capacity (FVC) and 32.9 vs. 33.5% reduction in forced expiratory volume in 1 s (FEV(1)) for groups 1 and 2, respectively]. There was an insignificant drop in oxygen saturation rates for both groups. The overall incidence of atelectasia was similar for group 1 and 2 (30.2 vs. 29.2%). Although the degree of atelectesia was found to be more severe in the placebo group, the difference was not statistically significant. We concluded that although preemptive analgesia decreased the need for postoperative analgesia, this had no effect on pulmonary functions and pulmonary complications.
