Trial reportTherapeutic advances in respiratory disease
Effects of walking with a portable oxygen concentrator on muscle oxygenation while performing normal or pursed-lip breathing in patients with interstitial lung disease: a randomized crossover trial.
Trial report in Therapeutic advances in respiratory disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundIn patients with interstitial lung disease (ILD), decreased oxygen saturation (SpO2) reduces physical performance and causes exertional dyspnea. Portable oxygen concentrator (POC) and pursed-lip breathing (PLB) have the potential to improve these parameters in ILD patients.
objectiveTo evaluate the effects of PLB while using a POC during walking in ILD patients.
designProspective, randomized crossover trial.
methodsWe compared two breathing techniques. Participants not trained in PLB received a familiarization session before the first 6-min walking test (6MWT). During the first visit, patients performed the 6MWT under natural breathing (NB1) without oxygen (O
resultsTwenty participants were recruited; half had exercise-induced desaturation (EID) and half normal SpO
conclusionAcute exposure to PLB did not improve symptoms, muscle oxygenation, or SpO
