A New Breathing Technique for Pain Management in Patients With Thoracic Trauma: A Randomised Trial.

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
backgroundPain management following thoracic trauma is important for optimal patient outcomes. One nostril inspiration (ONI) encourages slow inspiration through one nostril to minimise inspirational flow, avoiding rapid breathing movements which induce pain.
objectivesTo investigate the effects of ONI, added to standard physiotherapy management, on patients' reported pain levels, and on functional status, exercise capacity, pulmonary complications, adverse events, and hospital length of stay (LOS).
methodsA single-centre randomised trial was conducted. Adults with confirmed thoracic trauma, spontaneous breathing, and able to cooperate were recruited using consecutive sampling. Participants in two trauma wards received either standard physiotherapy or experimental care (standard physiotherapy plus ONI). A computer-generated randomisation list was used to determine ward allocation for standard (SC) and experimental care (EC). Allocation was 1:1. EC participants performed sets of 10 ONI breaths every second waking hour and when experiencing pain. Training was recorded in a diary. Outcomes were assessed on days 1-5 of admission. Descriptive and inferential analyses were performed.
resultsParticipants (n = 150; median age 31 (IQR 26-39) years; 92.7% male) had mostly sustained penetrating thoracic trauma from physical assault (82.7%). Most participants had intercostal drains in place. Both groups received a median of four physiotherapy sessions. EC participants performed ONI breathing at a median frequency of 2.8 (IQR: 2.1-3.6) times/day; 45% adhered to ≥ 75% of prescribed sessions. Pain decreased in both groups. On day 5, EC reported significantly lower pain (p = 0.01, moderate effect size d = 0.72). Participants practicing ONI ≥ 3 times/day had less pain on day 3 than those with lower adherence (p = 0.05). Secondary outcomes showed a slightly longer mean LOS for EC (5.0 vs. 4.5 days, p = 0.008). No between-group differences were found for pulmonary complications, functional or exercise capacity, or adverse events. All participants were discharged home.
conclusionEducation on repeated slow deep breathing exercise taught to patients with thoracic injury reduced pain, with ONI being one method of slow deep breathing. Those who adhered closely to the protocol had reduced pain from the third day of hospitalisation. ONI is a feasible and safe adjunct to standard physiotherapy that empowers patients to manage their respiratory pain.
