Predictive factors inhibiting recovery of the respiratory function after anatomical pulmonary resection.
Article in Surgery today, 2023. 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
purposeSome patients have worse actual observed postoperative (apo) respiratory function values than predicted postoperative (ppo) values. The present study therefore clarified the predictive factors that hinder the recovery of the postoperative respiratory function.
methodsThis study enrolled 255 patients who underwent anatomical pulmonary resection for lung cancer. A pulmonary function test (PFT) was carried out before surgery and at one, three, and six months after surgery. In each surgical procedures, the forced expiratory volume in 1 s (FEV1) ratio was calculated as the apo value divided by the ppo value. In addition, we investigated the predictive factors that inhibited postoperative respiratory function improvement in patients with an FEV1 ratio < 1.0 at 6 months after surgery.
resultsThe FEV1 ratio gradually improved over time in all surgical procedures. However, 49 of 196 patients who underwent a PFT at 6 months after surgery had an FEV1 ratio < 1.0. In a multivariate analysis, right side, upper lobe, segmentectomy and pleurodesis for prolonged air leakage were independent significant predictors of a decreased FEV1 ratio (p = 0.003, 0.006, 0.001, and 0.009, respectively).
conclusionPleurodesis was the only controllable factor that might help preserve the postoperative respiratory function. Thus, the intraoperative management of air leakage is important.
