Equipment errors: a prevalent cause for fallacy in blood pressure recording - a point prevalence estimate from an Indian health university.
Article in Indian journal of community medicine : official publication of Indian Association of Preventive & Social Medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundBlood pressure (BP) recording is the most commonly measured clinical parameter. Standing mercury sphygmomanometer is the most widely used equipment to record this. However, recording by sphygmomanometer is subject to observer and instrumental error. The different sources of equipment error are faulty manometer tube calibration, baseline deviations and improper arm bladder cuff dimensions. This is further compounded by a high prevalence of arm bladder miss-cuffing in the target population.
objectivesThe study was designed to assess the presence of equipment malcalibrations, cuff miss-matching and their effect on BP recording. MATERIALS AND
methodsA cross-sectional check of all operational sphygmomanometers in a health university was carried out for the length of the manometer tube, deviation of resting mercury column from "0" level, the width and length of arm bladder cuff and extent of bladder cuff-mismatch with respect to outpatient attending population.
resultsFrom the total of 50 apparatus selected, 39 (78%) were from hospital setups and 11 (22%) from pre-clinical departments. A manometer height deficit of 13 mm was recorded in 36 (92.23%) of the equipment in hospital and 11 (100%) from pre-clinical departments. Instruments from both settings showed significant deviation from recommended dimensions in cuff bladder length, width and length to width ratio (P < 0.001). Significant number of apparatus from hospital setups showed presence of mercury manometer baseline deviation either below or above 0 mmHg at the resting state (χ(2) = 5.61, D. F. = 1, P = 0.02). Positive corelationship was observed between manometer height deficit, baseline deviation and width of arm cuff bladder (Pearson correlation, P < 0.05). Bladder cuff mismatching in response to the target population was found at 48.52% for males and 36.76% for females. The cumulative effect of these factors can lead to an error in the range of 10-12 mmHg.
conclusionFaulty equipments and prevalent arm bladder cuff-mismatching can be important barriers to accurate BP measurement.
