Factors affecting abnormal triggering with non-invasive ventilators: A before-and-after study.
Article in The clinical respiratory journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06357780 (Closed-loop syncHronization vErsuS convenTional Synchronization in sPontaneously Breathing Adult Nonivasive Ventilation Patients), which is not on this map.

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

Abstract
introductionAbnormal triggering of non-invasive ventilator (NIV) is the main reason for increasing the possibility of patient intolerance and directly affecting the treatment effect.
objectiveTo investigate factors that affect abnormal triggering of NIV.
methodsThirty health volunteers from August 2018 to August 2019 were recruited. Two kinds of NIVs, Curative Flexo ST30 and Resmed Stellar™ 150, were selected, with S/T mode, respiratory rate of 10 bpm and inspiration time of 1.0 s. Every volunteer received ventilation in two ventilators, five oxygen flows (5/10/15/20/25 L/min), five support pressures (independent inspired positive airway pressure/expired positive airway pressure [IPAP/EPAP]: 8/4; 10/4; 12/4; 16/6; 20/8 cm H
resultsAll factors mentioned above affected normal triggering. With the increase of oxygen flow and support pressure, the frequency of auto-triggering and ineffective-triggering increased (P < 0.05). For Curative Flexo ST30 ventilator, when the oxygen injection site was proximal to the ventilator, the frequency of auto-triggering and ineffective-triggering is significantly lower than when it was proximal to the mask, whereas the result in Resmed Stellar™ 150 is totally different (P < 0.05).
conclusionWhen using Curative Flexo ST30 ventilator, the oxygen injection site should be proximal to the ventilator, whereas Resmed Stellar™ 150 ventilator is just the opposite. Attention should be paid to the effectiveness of ventilators when oxygen flow and support pressure settings are high, as abnormal triggers occur more frequently. Choosing the suitable mask is also important.
